Ladies/Gentlemen:

Iron Mountain Incorporated, a corporation organized and existing under the laws of Pennsylvania (the "Company"), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters named in Schedule I hereto (the "Underwriters"), for whom Bear, Xxxxxxx & Co. Inc. is acting as representative (the "Representative"), an aggregate of $150,000,000 principal amount of the Company's 6⁵/8% Senior Subordinated Notes due 2016 (the "Notes"). The Notes will be irrevocably and unconditionally guaranteed (the "Guarantees") by the subsidiaries of the Company listed in Schedule II hereto that have signed this Agreement (each, a "Guarantor" and, collectively, the "Guarantors"), and will be issued pursuant to an Indenture dated as of December 30, 2002 (the "Base Indenture"), as supplemented by a Second Supplemental Indenture thereto, to be dated as of the Closing Date (as hereinafter defined) among the Company, the Guarantors and The Bank of New York, as trustee (in such capacity, the "Trustee"). The Base Indenture, as supplemented by the Second Supplemental Indenture, is hereafter called the "Indenture." If you are the only Underwriter, all references herein to the Representative shall be deemed to be to the Underwriter.

1. Representations and Warranties of the Company and the Guarantors. The Company and each of the Guarantors jointly and severally represents and warrants to, and agrees with, each of the Underwriters that:

(a) The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (No. 333-75068), filed on December 13, 2001, as amended by Amendment No. 1 thereto, filed on February 11, 2002 (the "2002 Registration Statement") and a registration statement on Form S-3 (No. 333-105494) filed on May 23, 2003, as amended by Amendment No. 1 thereto, filed on June 5, 2003 (the "2003 Registration Statement"), for the registration of the Company's debt and other securities, as described therein, including the Notes, under the Securities Act of 1933, as amended (the "Securities Act"), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission (the "Rules and Regulations") under the Securities Act. Such registration statements, as so amended, have been declared effective by the Commission and copies have heretofore been delivered to the Underwriters. The 2002 Registration Statement and the 2003 Registration Statement, as so amended, including all information, if any, deemed to be a part thereof pursuant to Rule 430A of the Rules and Regulations, are collectively referred to herein as the "Registration Statement." No stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been initiated or, to the Company's knowledge, threatened by the Commission. The Company will file the Prospectus (as defined below) with the Commission pursuant to Rule 424(b) of the Rules and Regulations. The base prospectus contained

in the 2003 Registration Statement, at the time such registration statement was declared effective, as supplemented by the final prospectus supplement relating to the offering and sale of the Notes (the "Offering"), in the form in which it is to be filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, is hereinafter referred to as the "Prospectus," except that if any revised prospectus or prospectus supplement shall be provided to the Underwriters by the Company for use in connection with the Offering which differs from the Prospectus (whether or not such revised prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations), the term "Prospectus" shall refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. Any preliminary prospectus supplement (and the related base prospectus) relating to the Offering filed with the Commission pursuant to Rule 424 of the Rules and Regulations is hereafter called the "Preliminary Prospectus." Any reference herein to the Registration Statement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3, which were filed under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), on or before the effective date of the Registration Statement or the date of the Prospectus, as the case may be, and any reference herein to the terms "amend", "amendment" or "supplement" with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include (i) the filing of any document under the Exchange Act after the effective date of the Registration Statement or the date of the Prospectus, as the case may be, which is incorporated therein by reference and (ii) any such document so filed. All references in this Agreement to the Registration Statement and the Prospectus, or any amendments or supplements to any of the foregoing, shall be deemed to include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System ("XXXXX").

(b) At the time of the effectiveness of the Registration Statement or the effectiveness of any post-effective amendment to the Registration Statement, when the Prospectus is first filed with the Commission pursuant to Rule 424(b) or Rule 434 of the Rules and Regulations, when any supplement to or amendment of the Prospectus is filed with the Commission, when any document filed under the Exchange Act is filed and at the Closing Date (as hereinafter defined), the Registration Statement and the Prospectus and any amendments thereof and supplements thereto complied or will comply in all material respects with the applicable provisions of the Securities Act and the Rules and Regulations thereunder and the Exchange Act and the Rules and Regulations thereunder and did not and will not contain an untrue statement of a material fact and did not and will not omit to state any material fact required to be stated therein or necessary in order to make the statements therein (i) in the case of the Registration Statement, not misleading and (ii) in the case of the Prospectus, or the Preliminary Prospectus, if any, in light of the circumstances under which they were made, not misleading. When a related Preliminary Prospectus, if any, was first filed with the Commission (whether filed as part of the Registration Statement or any amendment thereto or pursuant to Rule 424(a) of the Rules and Regulations) and when any amendment thereof or supplement thereto was first filed with the Commission, such Preliminary Prospectus, if any, and any amendments thereof and supplements thereto complied in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the respective Rules and Regulations thereunder and did not contain an untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. No representation and warranty is made in this subsection (b), however, with respect to any information contained in or omitted from the Registration Statement or the Prospectus or related Preliminary Prospectus, if any, or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through you specifically for use therein ("Underwriters'

Information"). The parties acknowledge and agree that the Underwriters' Information consists solely of the material included in the fourth and sixth paragraphs under the caption "Underwriting" in the prospectus supplement portion of the Prospectus.

(g) All of the outstanding shares of capital stock of, or other ownership interests in, each of the Company's subsidiaries have been duly authorized and validly issued and are fully paid and non-assessable; all of such capital stock or other ownership interests (in the case of the Company's wholly-owned subsidiaries) or all of such capital stock or other ownership interests that the Company owns (in the case of less than wholly-owned subsidiaries as disclosed in the Prospectus or Schedule III hereto) are owned directly or indirectly by the Company, in each case, free and clear of any security interest, claim, lien, encumbrance or adverse claim of any nature, except as disclosed in the Prospectus or such as are not material to the business prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole; and Schedule III hereto sets forth the Company's ownership interest in any subsidiary (as defined in Regulation S-X Rule 1-02(x) of the Rules and Regulations) that is less than wholly-owned.

(h) This Agreement has been duly authorized, executed and delivered by the Company and the Guarantors and is a valid and binding agreement of the Company and the Guarantors

enforceable in accordance with its terms except as (i) rights to indemnity and contribution hereunder may be limited by applicable law, (ii) the enforceability hereof may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws affecting creditors' rights generally and (iii) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability.

(i) The Notes have been duly and validly authorized by the Company for issuance and sale pursuant to this Agreement, each Guarantee has been duly and validly authorized by the Guarantor to which it relates and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to the Underwriters against payment therefor as provided by this Agreement, the Notes and the Guarantees will be entitled to the benefits of the Indenture, and will be valid and binding obligations of the Company and the Guarantors, respectively, enforceable in accordance with their terms except as (i) the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws affecting creditors' rights generally and (ii) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability.

The Indenture conforms and any amendment or supplement thereto will conform with the requirements of the Trust Indenture Act of 1939, as amended.

(k) The Notes and Guarantees conform as to legal matters to the description thereof contained in the Prospectus.

(l) Neither the Company nor any of its subsidiaries is in violation of its respective charter or by-laws or comparable organizational documents or in default (and no condition exists which, with notice or lapse of time or both, would constitute a default) in the performance of any obligation, agreement or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any other agreement, indenture or instrument material to the conduct of the business of the Company and its subsidiaries, taken as a whole, to which the Company or any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective property is bound except for such defaults as could not, individually or in the aggregate, have a Material Adverse Effect.

(m) The execution, delivery and performance of this Agreement, the Indenture, the Notes and the Guarantees and compliance by the Company and the Guarantors with all the provisions hereof and thereof, as the case may be, and the consummation of the transactions contemplated hereby and thereby will not require any consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body (except as such may be required under the securities or Blue Sky laws of the various states or jurisdictions outside the United States), and will not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws or comparable organizational documents of the Company or any of its subsidiaries or any agreement, indenture or other instrument to which it or

any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective property is bound, or violate or conflict with any laws, administrative regulations or rulings or court decrees applicable to the Company, any of its subsidiaries or their respective property.

(n) Except as otherwise set forth in the Prospectus, there are no material legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or to which any of their respective property is the subject, and, to the best of the Company's knowledge, no such proceedings are threatened or contemplated.

(o) Neither the Company nor any of its subsidiaries is currently in violation of any foreign, federal, state or local law or regulation relating to the protection of human health or safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants ("Environmental Laws"), nor any federal or state law relating to discrimination in the hiring, promotion or pay of employees nor any applicable federal or state wages and hours laws, nor any provisions of the Employee Retirement Income Security Act of 1974, as amended, or the rules and regulations promulgated thereunder, which singly, or in the aggregate, could be reasonably expected to have a Material Adverse Effect on the Company or its subsidiaries, taken as a whole.

(p) The Company and each of its subsidiaries has such permits, licenses, franchises and authorizations of governmental or regulatory authorities ("Permits") including, without limitation, under any applicable Environmental Laws, as are necessary to own, lease and operate its respective properties and to conduct its respective business, except to the extent that the failure to have such Permits would not singly, or in the aggregate, have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole; the Company and each of its subsidiaries has fulfilled and performed all of its material obligations with respect to such Permits and no event has occurred which has or after notice or lapse of time would singly, or in the aggregate, have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole; and, except as described in the Prospectus, such Permits contain no restrictions that materially interfere with the business or operations of the Company or any of its subsidiaries as currently conducted.

(q) In the ordinary course of its business, when the Company or any of its subsidiaries acquires a fee interest in a parcel of real property located in the United States, the Company conducts a review of the property (generally consisting of a Phase I environmental assessment or similar study prepared on behalf of the seller or a predecessor owner of such property) to determine whether any conditions exist on the property that would constitute a violation of Environmental Laws or would require a material amount of capital or operating expenditures for clean-up, closure or compliance with Environmental Laws. In the ordinary course of its business, when the Company or any of its subsidiaries enters into a long-term real property lease for property located in the United States, the Company conducts an internal review, which may or may not result in a Phase I environmental assessment or similar study (although the Company would typically obtain a Phase I or similar study where the Company would have the right to acquire a fee interest in such real property), as it relates to such real property to determine whether any conditions exist on the property that would constitute a violation of Environmental Laws or would require a material amount of capital or operating expenditures for clean-up, closure or compliance with Environmental Laws. In the ordinary course of its business, the Company utilizes local counsel to obtain advice regarding owned or leased real property and local environmental matters outside the United States. On the basis of such reviews and advice, the Company has concluded that such associated costs and liabilities would not, singly or in the aggregate, have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole.

(r) Except as otherwise set forth in the Prospectus or such as are not material to the business prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, the Company and each of its subsidiaries has good and marketable title, free and clear of

all liens, claims, encumbrances and restrictions except liens for taxes not yet due and payable, to all property and assets described in the Prospectus as being owned by it. All leases to which the Company or any of its subsidiaries is a party are valid and binding and no default by the Company of any of its subsidiaries, by any other party, has occurred or is continuing thereunder, which might result singly, or in the aggregate, in a Material Adverse Effect to the Company or its subsidiaries, taken as a whole, and the Company and its subsidiaries enjoy peaceful and undisturbed possession under all such leases to which any of them is a party as lessee with such exceptions as do not have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole.

(s) The Company and each of its subsidiaries maintains, with insurers of recognized standing, reasonably adequate insurance against property and casualty loss, general liability, business interruption and such other losses and risks, in each case, in such amounts as are prudent and customary in the business in which they are engaged.

(u) Deloitte & Touche LLP, who are the current auditors of the Company, and RSM Xxxxxx Xxxxxx LLP who have certified certain financial statements of Iron Mountain Europe Limited, each are independent public accountants as required by the Securities Act, the Exchange Act and the respective Rules and Regulations thereunder.

(x) The pro forma financial statements and other pro forma financial information (including the notes thereto) included or incorporated by reference in the Registration Statement and in the Prospectus (i) present fairly the information shown therein, (ii) have been prepared in accordance with Article 11 of Regulation S-X and the related Rules and Regulations adopted by the Commission with respect to pro forma financial statements and (iii) have been properly compiled on the basis described therein, and the assumptions used in the preparation of such pro forma financial statements and other pro forma financial information (including the notes thereto) are reasonable and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein.

The chief executive officer and chief financial officer have indicated in each Report whether or not there were significant changes in internal controls or in other factors that could significantly affect internal controls subsequent to the Evaluation Date, including any corrective actions with regard to significant deficiencies and material weaknesses.

(ff) The Company and each of its subsidiaries maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management's general or specific authorization and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary at any time to amend or supplement the Prospectus or Registration Statement to comply with the Securities Act or the Rules and Regulations, or to file under the Exchange Act so as to comply therewith any document incorporated by reference in the Registration Statement or the Prospectus or in any amendment thereof or supplement thereto, the Company will notify you promptly and prepare and file with the Commission an appropriate amendment or supplement (in form and substance satisfactory to you) which will correct such statement or omission or which will effect such compliance and will use its best efforts to have any amendment to the Registration Statement declared effective as soon as possible.

(b) The Company will promptly deliver to each of the Underwriters such number of copies of any Preliminary Prospectus, the Prospectus, the Registration Statement, all amendments of and supplements to such documents, if any, all documents incorporated by reference in the Registration Statement and Prospectus or any amendment thereof or supplement thereto, as you may reasonably request.

(f) Whether or not required by the Rules and Regulations, so long as any Notes are outstanding and so long as the Indenture so requires, the Company will furnish to you at your reasonable request copies of all reports or other communications (financial or other) furnished to security holders, and to deliver to you (i) as soon as they are available, copies of any and all reports and financial statements furnished to or filed with the Commission or any national securities exchange on which any class of securities of the Company is listed; and (ii) such additional information concerning the business and financial condition of the Company as you may from time to time reasonably request (such financial statements to be on a consolidated basis to

(g) The Company will apply the proceeds from the sale of the Notes as set forth under "Use of Proceeds" in the Prospectus.

("Moody's") to reaffirm their respective credit ratings on the Company's outstanding senior subordinated debt, including for this purpose, the issuance of the Notes.

(k) The Company has not and will not (and has not permitted its affiliates to, and will cause its affiliates not to) take, directly or indirectly, any action which is designed to or which constitutes or which might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Notes and neither the Company nor any of its affiliated purchasers (as defined in Rule 100 of Regulation M under the Exchange Act) will take any action prohibited by Regulation M under the Exchange Act.

(l) The Company, during the period when the Prospectus is required to be delivered under the Act or the Exchange Act, will file all documents required to be filed with the Commission pursuant to Section 13, 14 or 15 of the Exchange Act within the time periods required by the Exchange Act and the rules and regulations thereunder.

Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company hereby agrees to pay all costs and expenses incident to the performance of the obligations of the Company hereunder, including the following: (i) the fees, disbursements and expenses of the Company's counsel and accountants in connection with the registration of the Notes under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any Preliminary Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of producing the Blue Sky Memoranda, all expenses in connection with the qualification of the Notes for offering and sale under state securities or Blue Sky laws as provided in Section 4(c) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iii) all fees and expenses in connection with the inclusion of the Notes in the book-entry system of The Depository Trust Company; (iv) all travel expenses of the Company's officers and employees and any other expense of the Company incurred in connection with attending or hosting meetings with prospective purchasers of the Notes; (v) fees paid to rating agencies in connection with the Notes and (vi) the filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, securing any required review by the National Association of Securities Dealers, Inc. of the terms of the sale of the Notes.

7. Indemnification.

(a) Each of the Company and the Guarantors shall indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including, but not limited to, attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or any amendment thereof, or related Preliminary Prospectus, if any, or the Prospectus, or in any supplement thereto or amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company will not be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through you expressly for use therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have including under this Agreement.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including, but not limited to, attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as originally filed or any amendment thereof, or related Preliminary Prospectus, if any, or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through you expressly for use therein. This indemnity will be in addition to any liability which any Underwriter may otherwise have including under this Agreement.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 7). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the

indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or reasonably could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or reasonably could have been the subject matter of such action 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 the indemnified party.

8. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company and the Underwriters shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting, in the case of losses, liabilities, claims, damages and expenses suffered by the Company any contribution received by the Company from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and the Underwriters from the offering of the Notes or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and (y) the underwriting discount received by the Underwriters bear to the total price to the public of the Notes, in each case as set forth in the Prospectus. The relative fault of the Company and of the Underwriters 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 on the one hand or the Underwriters on the other hand and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were

treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within in the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses (i) and (ii) of this Section 8. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. The obligations of the Underwriters to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Notes purchased by each of the Underwriters hereunder and not joint.

9. Default by an Underwriter.

(a) If one or more of the Underwriters shall fail at the Closing Date to purchase the Notes which it or they are obligated to purchase under this Agreement (the "Defaulted Notes") and such Defaulted Notes do not exceed in the aggregate 10% of the aggregate principal amount of the Notes, then each non-defaulting Underwriter shall purchase an aggregate amount of the Defaulted Notes equal to the proportion that the aggregate principal amount of Notes to be purchased by such Underwriter as set forth opposite such Underwriter's name on Schedule I hereto bears to the aggregate principal amount of Notes to be purchased by all non-defaulting Underwriters.

(b) Notwithstanding the foregoing, if the Defaulted Notes equal or exceed in the aggregate 10% of the aggregate principal amount of the Notes, then the non-defaulting Underwriters shall have the right, within 48 hours after the Closing Date, to make arrangements for one or more of such non-defaulting Underwriters to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon among such non-defaulting Underwriters and upon the terms herein set forth; provided that if the non-defaulting Underwriters shall not have completed such arrangements within such 48-hour period, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters or the Company and the Guarantors.

No action taken pursuant to this Section 9 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, any of the non-defaulting Underwriters or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangements.

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters and the Company contained in this Agreement, including the agreements contained in Section 5, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person

thereof or by or on behalf of the Company, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Notes to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement, including termination pursuant to Section 9 or 11 hereof.

11. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective upon the later of when (i) you and the Company shall have received notification of the effectiveness of the Registration Statement or (ii) the execution of this Agreement. Until this Agreement becomes effective as aforesaid, it may be terminated by the Company by notifying you or by you by notifying the Company. Notwithstanding the foregoing, the provisions of this Section 11 and of Sections 1, 5, 7 and 8 hereof shall at all times be in full force and effect.

(b) You shall have the right to terminate this Agreement at any time prior to the Closing Date: (A) if any domestic or international event or act or occurrence has materially disrupted, or in your opinion will in the immediate future materially disrupt, the market for the Company's securities or securities in general; or (B) if trading on the New York Stock Exchange (the "NYSE") or the NASDAQ National Market (the "NASDAQ")shall have been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE or the NASDAQ or by order of the Commission or any other governmental authority having jurisdiction; or (C) if a banking moratorium has been declared by any state or federal authority or if any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (D) if any downgrading shall have occurred in the Company's corporate credit rating or the rating accorded the Company's debt securities by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act;) or if any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities; or (E) (i) if there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (ii) if there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in (i) or (ii), in your sole judgment, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Notes on the terms and in the manner contemplated by the Prospectus.

(d) If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to (i) notification by you as provided in Section 11(a) hereof or (ii) Section 9(b) or 11(b) hereof), or if the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by you, reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and expenses of their counsel), incurred by the Underwriters in connection herewith.

13. Consent to Jurisdiction; Waiver of Immunities. Each of the Company and the Guarantors:

14. Parties. This Agreement shall inure solely to the benefit of, and shall be binding upon, the Underwriters and the Company and the controlling persons, directors, officers, employees and agents referred to in Section 7 and 8, and their respective successors and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provision herein contained.

1. Each of the Guarantors (i) has been duly incorporated or formed, (ii) is validly existing as a corporation, limited liability company or Massachusetts statutory business trust, (iii) is in good standing under the laws of its jurisdiction of incorporation or formation and (iv) has the corporate, limited liability company or statutory business trust power and authority required to carry on its business as it is described in the Registration Statement and the Prospectus.

2. The Company is duly qualified and is in good standing as a foreign corporation authorized to do business in each jurisdiction in which the nature of its business or its ownership or leasing of property requires such qualification, except where the failure to be so qualified would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

3. All of the issued and outstanding shares of capital stock of, or other ownership interests in, each of the Guarantors have been duly and validly authorized and issued and are fully paid and non-assessable, and are, to our knowledge, owned beneficially by the Company or its subsidiaries, free and clear of any perfected security interest or adverse claim, except to the extent described in the Prospectus or as would not be material to the business, prospects, financial conditions or results of operations of the Company and its subsidiaries, taken as a whole.

4. The Indenture has been duly authorized by all necessary corporate, limited liability company or statutory business trust, as the case may be, action of the Guarantors and, when the Notes are executed and authenticated in accordance with the provisions of the Indenture and delivered to the Underwriter against payment therefor as provided by the Underwriting Agreement, the Notes and the Guarantees will be entitled to the benefits of the Indenture, and will be valid and binding obligations of the Company and the Guarantors, respectively, enforceable in accordance with their terms.

5. The Underwriting Agreement has been duly delivered by the Company and duly authorized, executed and delivered by the Guarantors.

6. The Indenture has been duly delivered by the Company and duly authorized, executed and delivered by the Guarantors and is a valid and binding agreement of the Company and the Guarantors enforceable in accordance with its terms.

7. The statements under the "Description of the Notes," "Material United States Federal Income Tax Considerations" and "Underwriting" in the Prospectus, as amended or supplemented through the date hereof, insofar as such statements constitute a summary of legal matters, documents or proceedings referred to therein, fairly present the information so summarized with respect to such legal matters, documents and proceedings.

8. To our knowledge, no holder of any securities of the Company has the right to require registration of any security of the Company in connection with the filing of the Registration Statement or the issuance of the Notes.

9. The execution, delivery and performance of the Underwriting Agreement, the Indenture and the Notes, the performance of the Guarantees, and compliance by the Company and the Guarantors with all the provisions thereof and the consummation of the transactions contemplated thereby do not require any consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body (or pursuant to any consent decree known to us by which the Company or a Guarantor is bound), and do not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws or comparable organizational documents of the Company or any of the Guarantors or any agreement filed as an exhibit to the Registration Statement, the Company's Annual Report on Form 10-K for the year ended December 31,

Annex I-1

2002, including any amendments thereto (the "Annual Report") or the Company's Quarterly Report on Form 10-Q for the three-month period ended March 31, 2003, including any amendments thereto (the "Quarterly Report") or any other agreement or other document known to us under which the Company or any of the Guarantors has outstanding indebtedness for money borrowed in excess of $4,000,000, or violate or conflict with any laws, administrative regulations or rulings or, to our knowledge, court decrees applicable to the Company, any of the Guarantors or their respective property.

10. To our knowledge (A) no legal or governmental proceedings are pending or threatened to which the Company or any of the Guarantors is a party or to which any of their respective property is subject that are required to be described in the Prospectus and are not so described and (B) no contract or other document is required to be described in the Prospectus or filed as an exhibit to the Registration Statement that is not so described or filed.

11. Neither the Company nor any Guarantor is now, nor immediately after the offering of the Notes as described in the Prospectus will be, an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended, or is or will be subject to registration under the Investment Company Act.

12. The Registration Statement has become effective under the Act, and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose are pending before or threatened by the Commission. Any required filing of the Prospectus pursuant to Rule 424 under the Act has been made in accordance with said Rule 424. The Indenture has been duly qualified under the Trust Indenture Act.

13. The Registration Statement and the Prospectus and any supplements or amendments thereto (except for (i) the financial statements and the notes thereto and the schedules and other financial data included or incorporated by reference therein, and (ii) the part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) of the Trustee under the Trust Indenture Act, as to which we express no opinion), as of their respective effective date or issue date, complied as to form in all material respects with the requirements of the Act.

14. The Registration Statement, the Annual Report and the Quarterly Report (except for the financial statements and the notes thereto and the schedules and other financial data included or incorporated by reference therein, as to which we express no opinion) complied as to form when filed with the Commission in all material respects with the requirements of the Exchange Act.

Such opinion shall also recite that:

In the course of the Company's preparation of the Registration Statement and the Prospectus, we have participated in conferences with officers and other representatives of the Company, counsel for the Underwriter, representatives of the independent public accountants for the Company, and you, at which the contents of the Registration Statement and Prospectus and related matters were discussed and, although we are not passing upon, and do not assume responsibility for, the factual accuracy, completeness or fairness of the statements contained in the Registration Statement and Prospectus and have not made any independent check or verification thereof (except as set forth in paragraph 7), on the basis of the foregoing, we advise you that (except as to (i) the financial statements, schedules and other financial data included in the Registration Statement or the Prospectus, and (ii) that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) under the Trust Indenture Act, as to which you have not asked us to express, and as to which we do not express, any views) no facts have come to our attention that would lead us to believe that (x) the Registration Statement (including the Annual Report, the Quarterly Report and the Incorporated Documents), as of the time it became effective under the Act, as of March 21, 2003 at the time of filing the Annual Report, or on the date hereof, contained or contains an untrue statement of a material fact or omitted

Annex I-2

or omits to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading or (y) the Prospectus (including the documents incorporated by reference therein), at the time it was first provided to the Underwriter for use in connection with the offering of the Notes or at the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Annex I-3

ANNEX II

Form of Opinion of Company's General Counsel

1. The statements under the captions "Executive Compensation" and "Certain Relationships and Related Transactions" in the Company's Proxy Statement for the annual meeting of shareholders held on May 22, 2003 incorporated by reference in the Company's Annual Report on Form 10-K, as amended by Amendment No. 1 on Form 10-K/A, for the year ended December 31, 2002 and incorporated by reference in the Prospectus, as amended or supplemented, insofar as such statements constitute a summary of legal matters, documents or proceedings referred to therein, fairly present the information called for with respect to such legal matters, documents and proceedings;

2. The execution, delivery and performance of the Underwriting Agreement, the Indenture, the Notes and the Guarantees and compliance by the Company and the Guarantors with all the provisions thereof and the consummation of the transactions contemplated thereby do not require any consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body (except as such may be required under the securities or Blue Sky laws of the various states or jurisdictions outside the United States), and will not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws or comparable organizational documents of the Company or any of its subsidiaries or any agreement, indenture or other instrument to which it or any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective property is bound, or violate or conflict with any laws, administrative regulations or rulings or court decrees applicable to the Company, any of its subsidiaries or their respective property;

3. I do not know of (A) any legal or governmental proceeding pending or threatened to which the Company or any of its subsidiaries is a party or to which any of their respective property is subject which is required to be described in the Prospectus and is not so described, or (B) any contract or other document which is required to be described in the Prospectus or filed as an exhibit to the Registration Statement and is not so described or so filed;

4. To my knowledge, neither the Company nor any of its subsidiaries is in violation of its respective charter or by-laws or comparable organizational documents and, to my knowledge, neither the Company nor any of its subsidiaries is in default in the performance of any obligation, agreement or condition contained in any bond, debenture, note or other evidence of indebtedness or in any other agreement, indenture or instrument material to the conduct of the business of the Company and its subsidiaries, taken as a whole, to which the Company or any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective properties are bound;

5. All leases to which the Company or any of its subsidiaries is a party relating to real property in Massachusetts or California are valid and binding and no default has occurred or is continuing thereunder which might result in any material adverse change in the business prospects, financial condition or results of operations of the Company and its subsidiaries taken as a whole, and the Company and its subsidiaries enjoy peaceful and undisturbed possession under all such leases to which any of them is a party as lessee with such exceptions as do not materially interfere with the use made thereof by the Company or such subsidiary; and

6. To my knowledge, the Company and each of its subsidiaries has such permits, licenses, franchises and authorizations of governmental or regulatory authorities ("Permits"), including without limitation, under any applicable Environmental Laws, as are necessary to own, lease and operate its respective properties and to conduct its respective business in the manner described in the Prospectus; to my knowledge, the Company and each of its subsidiaries has fulfilled and performed all of its material obligations with respect to such Permits and no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any other material impairment of the rights of the holder of any such Permit, except as in each case as would

Annex II-1

not, singly or in the aggregate, have a material adverse effect (financial or otherwise) on the Company and its subsidiaries, taken as a whole; and, except as described in the Prospectus, such Permits contain no restrictions that materially interfere with the business or operations of the Company or any of its subsidiaries as currently conducted.

Such opinion shall also recite that:

I assisted in collecting information requested by your counsel and outside counsel to the Company and responded to inquiries concerning the Company and its subsidiaries raised by such counsel, and I have reviewed the Registration Statement and the Prospectus; although except as expressly set forth herein, I am not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus, no facts have come to my attention that would lead me to believe that (except as to (i) financial statements, schedules and other financial data contained therein and (ii) that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) under the Trust Indenture Act, as to which I express no view), (x) the Registration Statement (including the documents incorporated by reference therein), as of the time it became effective under the Securities Act, as of March 21, 2003 at the time of filing the Annual Report, or on the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading or (y) the Prospectus (including the documents incorporated by reference therein), at the time it was first provided to the Underwriters for use in connection with the offering of the Notes or at the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Annex II-2

ANNEX III

Form of Opinion of Special Pennsylvania Counsel to the Company

1. In reliance on the various certificates from the Commonwealth of Pennsylvania and a secretary's certificate from the Company, the Company is a corporation duly incorporated and validly subsisting under the laws of the Commonwealth of Pennsylvania and has the corporate power to own, lease and operate its properties and to conduct its business as described in the Prospectus, to execute, deliver and perform its obligations under the Underwriting Agreement and the Indenture and to consummate the transactions contemplated by the Underwriting Agreement and by the Prospectus.

2. The Underwriting Agreement and the Indenture have been duly executed by the Company.

3. The execution, delivery and performance of the Underwriting Agreement, the Indenture and the Note, and the consummation of the transactions contemplated therein, have been duly authorized by all necessary corporate action on the part of the Company and will not (i) violate the provisions of the Articles of Incorporation or Bylaws of the Company or (ii) violate any present statute, rule or regulation promulgated by the Commonwealth of Pennsylvania which in our experience is normally applicable both to general business corporations which are not engaged in regulated business activities and to transactions of the type contemplated by the Registration Statement, the Prospectus, the Indenture, the Note and the Underwriting Agreement (collectively, the "Law").

4. The statements under the captions "Description of Our Capital Stock" and "Description of Certain Provisions of Pennsylvania Law and Our Articles of Incorporation and Bylaws" in the Prospectus and "Indemnification of Directors and Officers" in the Registration Statement have been reviewed by us, and insofar as such statements constitute summaries of certain provisions of the Articles of Incorporation or Bylaws of the Company, statutes, rules, regulations or statements of Law, they constitute fair summaries thereof.

5. No consent or approval of, or notice to or filing with, any governmental authority or agency of the Commonwealth of Pennsylvania under any provision of applicable Law is required by the Company in connection with the execution and delivery of the Indenture or the issuance of the Note pursuant to the Indenture, or the offer and sale of the Note pursuant to the Underwriting Agreement, except those already obtained or made or those described in the Prospectus.
