Ladies and Gentlemen:

IDI Acquisition Corp., a Delaware corporation, (the "Company"), which will be merged with and into InterDent Service Corporation, a Washington corporation ("Service" and together with the Company, the "Issuers"), proposes to issue and sell to Xxxxxxxxx & Company, Inc. (the "Initial Purchaser") an aggregate of $80,000,000 million principal amount of the Issuers' 10³/4% Senior Secured Notes due 2011 (the "Series A Notes"), subject to the terms and conditions set forth herein. The Series A Notes and the Series B Notes (as defined below) (the Series A Notes and the Series B Notes being collectively referred to herein as the "Notes") will be issued pursuant to an Indenture, dated as of the Closing Date (as defined below) (the "Indenture"), among the Company, Service, the Guarantors (as defined below) and Xxxxx Fargo Bank, National Association, as trustee (the "Trustee").

Substantially concurrent with the sale of the Notes, Service proposes to enter into a new or amended senior secured credit facility, by and among Service and Xxxxx Fargo Foothill, Inc. ("Foothill") initially providing for up to $10.0 million of revolving credit borrowings by Service (the "Credit Facility"). The Issuers have agreed to secure the Notes by granting to Xxxxx Fargo Bank, National Association, as collateral agent (the "Collateral Agent"), for the benefit of the holders of the Notes and the Trustee (collectively, the "Secured Parties"), security interests in or pledges of (the "Security Interests") the Collateral (as such term is defined in the Description of the Notes section of the Final Offering Circular (as defined below)). In connection with the execution and delivery of the Credit Facility, Service, Foothill, the Trustee and the Collateral Agent will enter into an Intercreditor Agreement, which shall be dated as of the Closing Date (as defined below) (the "Intercreditor Agreement").

On November 10, 2004, Xxxxxx Xxxxxxxxx Capital Partners II, L.P. ("Xxxxxx"), B III-A Capital Partners, L.P. ("B III-A"), B IV Capital Partners, L.P. ("B IV") and GMAM Investment Funds Trust II ("GM Account" and collectively with B III-A and B IV, the "Sellers"), InterDent, Inc., a Delaware corporation ("Parent"), and Pleasant Street Investors, LLC entered into a stock purchase agreement (the "Stock Purchase Agreement"). Pursuant to the Stock Purchase Agreement, Xxxxxx has the right to designate an affiliate to purchase the capital stock of Parent owned by the Sellers, and will so designate the Company. Substantially concurrent with the issuance of the Series A Notes, the Company will purchase the capital stock of Parent owned by the Sellers pursuant to the Stock Purchase Agreement and substantially concurrently therewith will be merged with and into Service (the "Merger") pursuant to an Agreement and Plan of Merger, between the Company, Service and Parent (the "Merger Agreement"). Service will survive the Merger and, upon the filing of the appropriate Merger documents with the Delaware Secretary of State and Washington Secretary of State, will assume all of the obligations of the Company under the Indenture, the Notes and the Registration Rights Agreement (as defined below). In addition, substantially concurrent with the closing of the Merger, Parent and Xxxxxx will enter into a Securities Purchase Agreement (the "Securities Purchase Agreement") pursuant to which, among other things, Parent will sell to Xxxxxx shares of its preferred stock for $3.5 million,

which proceeds will be contributed to, and accounted for by, Service as common equity. Following the transactions contemplated by the Stock Purchase Agreement, the Merger Agreement, the Credit Facility and the Securities Purchase Agreement (the "Transactions"), all of the capital stock of Parent, except for shares held by Parent's management, will be owned by Xxxxxx and its affiliates.

The Issuers' obligations under the Series A Notes, including the due and punctual payment of principal, premium, interest and liquidated damages, if any, on the Series A Notes, will be unconditionally, jointly and severally guaranteed (the "Series A Guarantees" and together with the Series B Guarantees (as defined below), the "Guarantees") by Parent, and any future domestic guarantors party to the Indenture (each a "Guarantor" and, collectively the "Guarantors").

The Issuers and Parent hereby jointly and severally agree with the Initial Purchaser as follows:

The Issuers and Parent shall use their best efforts to prevent the issuance of any stop order or order suspending the qualification or exemption of any of the Series A Notes under any state securities or Blue Sky laws, and if at any time any state securities commission or other federal or state regulatory authority shall issue an order suspending the qualification or exemption of any Series A Notes under any state securities or Blue Sky laws, the Issuers and Parent shall use their best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

(d) If, during the period referred to in Section 5(c), any event shall occur or condition shall exist as a result of which, in the judgment of Service or Parent or in the reasonable judgment of counsel to the Initial Purchaser, it becomes necessary to amend or supplement the Offering Circular in order to make the statements therein, in the light of the circumstances when the Offering Circular is delivered to an Eligible Purchaser, not misleading, or if, in the reasonable judgment of counsel to the Initial Purchaser, it is necessary to amend or supplement the Offering Circular to comply with any applicable law, Service will promptly notify the Initial Purchaser and prepare an appropriate amendment or supplement to the Offering Circular so that the statements therein, as so amended or supplemented, will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Offering Circular will comply with applicable law, and to furnish to the Initial Purchaser and such other persons as the Initial Purchaser may designate such number of copies thereof the Initial Purchaser may reasonably request.

(y) Service, Parent and the Subsidiaries have not violated any foreign, federal, state or local law or regulation relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants ("Environmental Laws"), except for such violations which, singly or in the aggregate, would not have a Material Adverse Effect, and there exists no fact, and no event has occurred, which has or is reasonably likely to result in material liability (including, without limitation, alleged or potential liability for investigatory costs, cleanup costs, governmental response costs, natural resource damages, property damages, personal injuries or penalties) of Service, Parent or the Subsidiaries arising out of, based on or resulting from the presence or release into the environment of any hazardous material (including without limitation any pollutant or contaminant or hazardous, dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of any Environmental Law) or any violation of any Environmental Law, except such as could not reasonably be expected to have a Material Adverse Effect.

Each such Authorization is valid and in full force and effect and Service, Parent and the Subsidiaries are in material compliance with all the terms and conditions thereof and with the rules and regulations of the authorities and governing bodies having jurisdiction with respect thereto.

"PRIOR TO EXPIRATION OF THE 40-DAY DISTRIBUTION COMPLIANCE PERIOD (AS DEFINED IN REGULATION S ("REGULATION S") UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")), THIS SECURITY MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES (AS DEFINED IN REGULATION S) OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, A U.S. PERSON (AS DEFINED IN REGULATION S), EXCEPT TO A PERSON REASONABLY BELIEVED TO BE A "QUALIFIED INSTITUTIONAL BUYER" (AD DEFINED IN RULE 144A ("RULE 144A") UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A AND THE INDENTURE REFERRED TO HEREIN OR TO AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3) or (7) OF REGULATION D UNDER THE SECURITIES ACT).

The Initial Purchaser acknowledges that the Issuers and Parent and, for purposes of the opinions to be delivered to the Initial Purchaser pursuant to Section 9, counsel to the Issuers and Parent and counsel to the Initial Purchaser will rely upon the accuracy and truth of the foregoing representations and the Initial Purchaser hereby consents to such reliance.

8. Indemnification.

(a) The Issuers and Parent, jointly and severally, agree to indemnify and hold harmless the Initial Purchaser, its affiliates (including each person, if any, who controls the Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act), directors, officers, partners, shareholders, counsel, employees and agents from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in the Final Offering Circular (or any amendment or supplement thereto), the Preliminary Offering Circular or any Rule 144A Information provided by the Issuers or Parent to any holder or prospective purchaser of Series A Notes pursuant to Section 5(i) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to the Initial Purchaser furnished in writing to the Issuers or Parent by the Initial Purchaser, it being expressly understood and agreed that the only such information furnished by the Initial Purchaser to the Issuers or Parent consists of the information described in Section 8(b).

(b) The Initial Purchaser agrees to indemnify and hold harmless the Issuers and Parent, their respective directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Issuers or Parent, to the same extent as the foregoing indemnity from the Issuers and Parent to the Initial Purchaser but only 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 Preliminary Offering Circular or the Final Offering Circular, 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, 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 any such loss, liability, claim, damage or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information relating to the Initial Purchaser furnished to the Issuers and Parent in writing by or on behalf of the Initial Purchaser expressly for use therein, provided, however, that in no case shall the Initial Purchaser be liable or responsible for any amount in excess of the discounts and commissions received by the Initial Purchaser, as set forth on the cover page of the Offering Circular. The Issuers and Parent hereby acknowledge that the only information that the Initial Purchaser has furnished to the Issuers expressly for use in the Preliminary Offering Circular and the Final Offering Circular, or any amendment or supplement to either of them, are the first sentence of the third paragraph and the first sentence of the sixth paragraph of the "Plan of Distribution" section of the Offering Circular.

(c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the "Indemnified Party"), the Indemnified Party shall promptly notify the person against whom such indemnity may be sought (the "Indemnifying Party") in writing and the Indemnifying Party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), the Initial Purchaser shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Initial Purchaser). Any Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the employment of such counsel shall have been specifically authorized in writing by the Indemnifying Party, (ii) the Indemnifying Party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the Indemnified Party or (iii) the named parties to any such action (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party shall not have the right to assume the defense of such action on behalf of the Indemnified Party). In any such case, the Indemnifying Party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Indemnified Parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Initial Purchaser, in the case of the parties indemnified pursuant to Section 8(a), and by the Issuers, in the case of parties indemnified pursuant to Section 8(b). The Indemnifying Party shall indemnify and hold harmless the Indemnified Party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the Indemnifying Party shall have received a written request from the Indemnified Party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the Indemnifying Party) and, prior to the date of such settlement, the Indemnifying Party shall have failed to comply with such reimbursement request. 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 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 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.

(d) To the extent the indemnification provided for in this Section 8 is unavailable to an Indemnified Party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and Parent, on the one hand, and the Initial Purchaser on the other hand from the offering of the Series A Notes or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Issuers and Parent, on the one hand, and the Initial Purchaser, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and Parent, on the one hand and the Initial Purchaser, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Series A Notes (after underwriting discounts and commissions, but before deducting expenses) received by the Issuers and Parent, and the total discounts and commissions received by the Initial Purchaser bear to the total price to investors of the Series A Notes. The relative fault of the Issuers and Parent, on the one hand, and the Initial Purchaser, on the other hand, 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 Issuers and Parent, on the one hand, or the Initial Purchaser, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Issuers, Parent and the Initial Purchaser agree that it would not be just and equitable if contribution pursuant to Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. No person guilty of fraudulent misrepresentation (within 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.

(f) The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity.
