("NIS"), DIGIRAD IMAGING SYSTEMS, INC. ("Purchaser"), DVI FINANCIAL SERVICES, INC. ("Assignee") and U.S. TRUST COMPANY, NATIONAL ASSOCIATION, ("Escrow Agent") (collectively, "Parties"). WHEREAS, NIS is indebted to Assignee on account of certain indebtedness owed by NIS to Assignee, which indebtedness is secured by certain assets of NIS; WHEREAS, NIS, an affiliate of NIS, Cardiovascular Concepts, P.C. ("CVC"), and Purchaser are parties to an Asset Purchase Agreement (the "A/P Agreement") pursuant to which Purchaser agreed to purchase and NIS (and CVC) agreed to sell to Purchaser certain assets comprising the "Mobile Business" of NIS and/or CVC, some or all of which assets are encumbered by a lien in favor of Assignee; WHEREAS, out of the agreed upon purchase price of $725,000, the sum of $100,000 was to be and hereby is deposited into escrow with Escrow Agent subject to a first priority lien and security interest in favor of Purchaser to secure the maintenance obligations of NIS owed to Purchaser, and subject the liens and security interests of Assignee which are subordinate to those in favor of Purchaser, and subject to the terms this Agreement in order to fund certain maintenance obligations of NIS with respect to certain equipment encumbered by a lien in favor of Assignee, but which equipment is being leased to Purchaser, not purchased by Purchaser (the "Leased Equipment") as set forth in an "Equipment Lease Agreement" between NIS and Purchaser which is to be executed concurrently with the A/P Agreement; and WHEREAS, Escrow Agent has indicated its willingness to act as escrow holder for the compensation set forth in EXHIBIT 1 attached hereto. NOW, THEREFORE, the Parties agree as follows: ARTICLE I 1. APPOINTMENT AND ACCEPTANCE. The Purchaser, NIS and Assignee hereby appoint Escrow Agent as escrow agent for the purposes and upon the terms and conditions hereinafter set forth. Escrow Agent hereby accepts such appointment and agrees to act as escrow agent hereunder and to hold, invest and dispose of any funds received by it hereunder in accordance with the terms and conditions hereinafter set forth. 2. OPENING OF ESCROW FUND. On or before the Closing Date defined in the A/P Agreement, NIS will cause to be delivered to Escrow Agent the sum of $100,000 (the "Escrow Fund") to be deposited in a federally insured, interest-bearing account. 1 <Page> 3. PURPOSE OF AGREEMENT. The Purchaser, NIS and Assignee represent to Escrow Agent that (a) this Agreement has been executed and the deposit of the Escrow Fund hereunder has been made pursuant to the A/P Agreement for the purpose of providing a fund for the maintenance of the Leased Equipment (which is encumbered by a lien in favor of Assignee) in the event NIS should fail to perform its maintenance obligations under the A/P Agreement and the Equipment Lease Agreement ("Maintenance Claims"), and (b) CVC has no interest in the Escrow Fund. ARTICLE II 1. DISBURSEMENTS FOR MAINTENANCE. During the term of this Escrow (and subject to paragraphs II.2 and Article VII, below), Escrow Agent shall disburse such sums as are demanded by Purchaser in accordance with the following procedure: a. If NIS fails to maintain the Leased Equipment as required by the Equipment Lease Agreement, Purchaser shall give telephonic or fax notice of the deficiency in performance of maintenance to both NIS and Assignee, and (if telephonic notice was used) shall immediately send a written confirmation thereof to NIS via facsimile (a "Maintenance Notice"). b. If NIS is not able to give adequate assurance to Purchaser within 24 hours of receipt of the telephonic or written notice of the maintenance deficiency that Purchaser will cure the deficiency, Purchaser may contract with a third party to provide the necessary maintenance to the Leased Equipment, which contract may either be for a one-time only servicing of the equipment, or may be a contract to provide service for the remainder of the term of the Equipment Lease Agreement, in Purchaser's sole and absolute discretion. c. Simultaneously with obtaining services from a third party, Purchaser shall (i) send to Escrow Agent a copy of the Maintenance Notice and a copy of the service contract or invoice for repair (if the Leased Equipment was already repaired at the cost of Purchaser), and (ii) send to Assignee and NIS a copy of the service contract or invoice for repair (if the Leased Equipment was already repaired at the cost of Purchaser). d. Upon receipt of a copy of the service contract or invoice for repair (if the Leased Equipment was already repaired at the cost of Purchaser), Escrow Agent shall (i) promptly reimburse Purchaser for any sums already paid for maintenance by Purchaser using the funds in the Escrow Fund, and (ii) in the event a service contract was entered into, arrange for payments thereunder as and when they are due under the contract. 2 <Page> e. The sole means by which NIS or Assignee may bar release of funds from the Escrow Fund is by obtaining an appropriate court order on not less than 1 Business Day's notice to Purchaser enjoining payment from the Escrow Fund on the basis that either (i) NIS did not breach its maintenance obligation, or (ii) the cost of repair or the maintenance contract terms are unreasonable. 2. EFFECT OF END OF EQUIPMENT LEASE AGREEMENT. Unless directed otherwise by Purchaser or by an order of a court of competent jurisdiction, 30 days after the end of the lease term set forth in the Equipment Lease Agreement, all undisbursed funds remaining in the Escrow Fund (net of sums payable to Escrow Agent as set forth in this Agreement and in EXHIBIT 1) shall be delivered to Assignee at the address provided in this Agreement or at such other address as Assignee may provide to Escrow Agent in writing. ARTICLE III The Escrow Agent undertakes to perform only the duties expressly set forth in this document. The Escrow Agent shall not be bound by any waiver, modification, amendment, termination, cancellation or revision of this Escrow Agreement, unless the foregoing is in writing, signed by all the parties to this Escrow Agreement, and the prior consent of the Escrow Agent has been obtained. The Escrow Agent shall not be bound by any assignment of the rights, duties or obligations under this Escrow Agreement by any party unless, the Escrow Agent receives prior written notification of such assignment and the Escrow Agent gives prior written consent to such assignment. The Escrow Agent shall perform any act ordered by a court of competent jurisdiction. ARTICLE IV NIS agrees to indemnify the Escrow Agent for, and to hold Escrow Agent harmless, against any and all, fees, expenses, claims, suits, actions, proceedings investigations judgments, arbitration decisions, deficiencies, damages, awards, settlements, reasonable legal fees and expenses of attorney(s) chosen by the Escrow Agent, liabilities and expenses incurred based upon, but not limited to, a mistake of fact or law, act, performance, non-performance, alleged act, alleged omission, actual omission, act or omission based upon the advice of counsel or any other cause committed while performing any and all duties in connection with and under this Escrow Agreement. In addition, except where Escrow Agent is guilty of willful misconduct or negligence, the Escrow Agent shall receive full indemnification protection from: a. Purchaser when relying upon any certificate, instruction, statement, request, notice, advice, direction, agreement, instrument, document, signature of Purchaser believed by the Escrow Agent to be genuine, or any assumption by the Escrow Agent that any person purporting to give the Escrow Agent any of the foregoing on behalf of Purchaser in accordance with the provisions herein has been duly authorized to do so; and 3 <Page> b. Assignee when relying upon any certificate, instruction, statement, request, notice, advice, direction, agreement, instrument, document, signature of Assignee believed by the Escrow Agent to be genuine, or any assumption by the Escrow Agent that any person purporting to give the Escrow Agent any of the foregoing on behalf of Assignee in accordance with the provisions herein has been duly authorized to do so. This Escrow Agreement hereby grants to the Escrow Agent a lien on the Escrow Fund (which lien shall become invalid and unenforceable with respect to any portion of the Escrow Fund wired or delivered to Purchaser which shall receive such funds free and clear of such security interest) to enable the Escrow Agent to secure the aforementioned indemnity. The Escrow Agent shall be under no duty to institute or defend any type of proceeding which may arise regarding this Escrow Agreement ARTICLE V The Escrow Agent may resign and be discharged from the duties and obligations under this agreement at any time by giving no fewer than fifteen (15) days written notice of such resignation to the parties herein, specifying the date when such resignation shall take effect.

Upon receipt of such instruction, the Escrow Agent shall, as soon as all fees are received in full, promptly deliver all of the escrowed Documents and the Escrow Funds to such successor escrow agent in accordance with such instructions. Upon receipt of the Escrow Fund, the successor escrow agent shall be bound by all the provisions herein and shall promptly deliver a written instrument to each of the parties detailing the terms in which the successor escrow agent agrees to be bound.

("LESSEE"), and NUCLEAR IMAGING SYSTEMS, INC., a Pennsylvania corporation ("LESSOR") based on the following facts and understandings: WHEREAS, Lessor is a debtor and debtor in possession in chapter 11 case No. 00-19698 (the "Bankruptcy Case") pending in the United States Bankruptcy Court for the Eastern District of Pennsylvania (the "Bankruptcy Court"); WHEREAS, Lessor, as part of its larger business, operates a service that provides mobile delivery of diagnostic cardiac services, diagnostic imaging equipment and related technical services to physicians providing cardiology services (the "Mobile Business"); WHEREAS, Lessee has purchased certain assets of Lessor pertaining to the Mobile Business, on the terms and conditions set forth in an "Asset Purchase Agreement" (the "A/P Agreement") approved by the Bankruptcy Court; WHEREAS, certain assets not purchased under the A/P Agreement but relating to the Mobile Business is comprised of equipment which is either subject to a lien and security interest in favor of DVI Financial Services, Inc. ("DVI") or subject to a lease under which DVI is the Lessor, and certain of which equipment Lessee desires to lease for a period of time until Lessee can replace such equipment; NOW, THEREFORE, in consideration of the premises and the mutual covenants and promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: I. THE LEASE 1.1 LEASE OF EQUIPMENT. Set forth on SCHEDULE 1 attached hereto (the "SCHEDULE") is a list of ten (10) "Systems" as identified by a separate line item on SCHEDULE 1. During the "Term" of this Lease (as defined in Section 1.2), Lessor shall be obligated to lease to Lessee and Lessee shall lease from Lessor, the Systems identified on SCHEDULE 1 as System nos. 1, 5, 11, and 12, subject to the terms and conditions set forth herein and subject to Lessor's maintenance obligation which maintenance obligation may be addressed, in part, by the ability of Lessor to substitute any of the other Systems listed on SCHEDULE 1 to replace any of System nos. 1, 5, 11, and/or 12 should one or more of those four Systems require maintenance or repair more efficiently addressed by the substitution of any of System nos. 6, 8, 9, 10, 13, or 14 for a malfunctioning System. Such substitution, and the ability of Lessor to effect such a substitution, shall not affect or increase the rent obligation payable by Lessee hereunder. The Systems leased to Lessee, together with all substitutions, replacements, repairs, parts and attachments, improvements and accessions thereto are referred to as the "EQUIPMENT". Lessor shall at all times retain such legal or equitable rights in the Equipment as it had prior to the execution of this Agreement, it being expressly agreed by both parties that this Agreement and the lease it represents (the "LEASE") is an agreement of lease (and/or sublease) only. 1.2 TERM OF LEASE. The Term of this Lease shall begin on the date when the conditions precedent to the effectiveness hereof (the "Commencement Date") have been satisfied as set forth in Section 1.6 below and shall continue until November 30, 2000, subject to extension on a week to week , and a System by System basis if on or before the date that is 3 calendar days before the last day of the Term, Lessee sends notice to Lessor via fax or hand delivery that the Lease will be extending the Term as to specified Systems for another weeks, and such extension shall then extend the "Term" to the date specified in the notice as to the indicated System. The term "COMMENCEMENT DATE" shall mean the date upon which all of the following are true: (a) the A/P Agreement 1. <Page> has been approved by the Bankruptcy Court and all conditions precedent to the effectiveness of the A/P Agreement shall have been satisfied, (b) this Agreement has been approved by the Bankruptcy Court, and (c) Lessor has delivered possession of the Equipment to Lessee. 1.3 RENTAL PAYMENTS. Lessee shall pay Lessor Rent at a rate of $500 per week per System included as part of the leased "Equipment" (I.E., four Systems as of the Commencement Date), payable in arrears on October 31, 2000 and November 30, 2000, and thereafter on the last day of each weekly extension, if any. The first payment for the period between the Commencement Date and November 1, 2000 shall be equal to a pro rated rental payment based on $500 per System divided by 7 multiplied by the actual number of days from the Commencement Date to November 1, 2000. All Rent and other amounts payable by Lessee to Lessor hereunder shall be paid to Lessor's designee and assignee, DVI, by check payable to DVI, at the address specified above, or at such other place (or person or entity) as DVI may designate in writing to Lessee from time to time. 1.4 RETURN OF EQUIPMENT. Upon expiration of the Term, Lessee shall immediately return the Equipment to Lessor's designee, which designee shall be DVI unless DVI designates otherwise in writing. In other words, the designation of DVI as the designee for the return of the Equipment may altered only by a writing signed by DVI. Lessee shall bear no expense for the return of the Equipment. Lessee's sole responsibility shall be to make the Equipment available for pick up by DVI or its designee at a mutually convenient time. 1.5 ABATEMENT OF RENT. Notwithstanding the foregoing paragraphs 1.2, 1.3, and 1.4, Lessee may elect at any time during the Term to return individual Systems as identified on Schedule 1 without terminating the Lease or the Term (except as to the individual System) and receive an abatement of the Rent payable to DVI equal to $500 per System returned per week. To make this election for any given individual System, on or before the Monday of the calendar week at the end of which, Lessee intends to return a particular System, Lessee shall notify DVI and Lessor in writing of the election to return a particular identified System and Lessee shall make the System available to DVI for pick up on the following Monday or on such other date as is mutually agreed to by DVI and Lessee. No matter when the designated System is picked up by DVI, however, all obligations of Lessee with respect to such designated System shall cease after the first to occur of (1) the date DVI picks up the System, and (2) the last calendar day of the week which marks the end of the Term for such system due to termination in accordance with this Section 1.5. The abatement of Rent shall be effective as of the Monday after notice in accordance with this Paragraph 1.5 is given. 1.6 CONDITIONS PRECEDENT TO LESSEE'S OBLIGATIONS. It shall be a condition precedent to each and every obligation of Lessee hereunder, that each of the following conditions precedent shall be an remain satisfied (unless waived in writing by Lessee): (a) The Bankruptcy Court with jurisdiction over the Lessor's bankruptcy case shall have approved the execution and performance by Lessor of this Agreement , of the A/P Agreement and of all the "Acquisition Documents" executed pursuant to the A/P Agreement pursuant to an order or orders that are in form and substance satisfactory to Lessee and which order or orders shall be final and non-appealable (and as to which no appeal has been taken, I.E., a "Final Order"); (b) Lessor shall have executed and delivered this Agreement, the A/P Agreement, and each of the Acquisition Documents to Lessee; (c) The Maintenance Escrow Agreement (or counterparts thereof) shall have been fully executed by all parties thereto, shall have been approved by the Bankruptcy Court (as one of the Acquisition Documents) by a Final Order, and the Maintenance Escrow shall have been established and funded, in each case to the satisfaction of Lessee; (d) All Leased Equipment shall have been delivered to Lessee; (e) All representations and warranties set forth herein shall be true and correct; and (f) No default or Event of Default by Lessee or any affiliate of Lessee shall have occurred hereunder, under the A/P Agreement, under any Acquisition Document, or under any other agreement or 2. <Page> document executed pursuant to any of them (including the Consulting Agreement signed by Jeffrey Mandler and the "MMC Services Agreement" signed by Medical Management Concepts, Inc.). II. LESSEE OBLIGATIONS 2.1 RENT; PAYMENTS UNCONDITIONAL. LESSEE'S SOLE PAYMENT OBLIGATION UNDER THIS LEASE IS FOR RENT, INSURANCE (AS PROVIDED IN SECTION 2.6) AND OTHER SPECIFICALLY IDENTIFIED PAYMENT OBLIGATIONS. ALL OTHER COSTS, EXPENSES AND LIABILITIES RELATING TO THE EQUIPMENT, INCLUDING IN RESPECT OF TAXES (IF ANY) AND MAINTENANCE, SHALL BE BORNE SOLELY BY LESSOR. LESSEE'S OBLIGATION TO PAY ALL SUCH RENT AND OTHER SUMS HEREUNDER, AND THE RIGHTS OF LESSOR (OR DVI) IN AND TO SUCH PAYMENTS, SHALL BE ABSOLUTE AND UNCONDITIONAL, AND SHALL NOT BE SUBJECT TO ANY ABATEMENT, REDUCTION, SETOFF, DEFENSE, COUNTERCLAIM, INTERRUPTION, DEFERMENT OR RECOUPMENT, FOR ANY REASON WHATSOEVER. 2.2 USE OF EQUIPMENT. Lessee shall use the Equipment solely in the conduct of its business, in a manner and for the use contemplated by the manufacturer thereof, and in compliance with all Requirements of Law of every Governmental Authority having jurisdiction over the Equipment or Lessee and with the provisions of all policies of insurance carried by Lessee pursuant to Section 2.6. 2.3 DELIVERY; INSTALLATION; RETURN; MAINTENANCE AND REPAIR. Lessor shall be solely responsible, at its own expense, for (a) making the Equipment available to Lessee, and (b) the installation, de-installation, maintenance and repair of the Equipment, such that the Equipment remains in excellent working order and repair in keeping with the standards required by law and all Governmental Authorities, and in keeping with the prudence dictated by the nature of the Equipment as medical equipment. Lessor and/or DVI should it so elect, shall be solely responsible, at its own expense, for re-taking possession of the Equipment upon expiration or termination of the Lease Term and/or should Lessee make an election as described in Paragraph 1.5. In the event that Lessor does not perform maintenance services itself, Lessor shall ensure that the Equipment is covered by a maintenance agreement, to the extent available, with the manufacturer of the Equipment or other party reasonably acceptable to Lessee. If Lessor or its agent fails to maintain the Equipment in accordance with the standards set forth in this Agreement, and if no substitute System is provided to Lessee that is satisfactory to Lessee, then Lessee may arrange for such repair and maintenance and shall be reimbursed therefor from the escrow (the "MAINTENANCE ESCROW") established and funded pursuant to the A/P Agreement and the escrow agreement executed pursuant thereto. Should any of the Equipment fail to be returned to DVI in good repair, condition and working order, ordinary wear and tear excepted, Lessee shall have no liability therefor UNLESS Lessee was grossly negligent or reckless in its use of the Equipment, but DVI may be compensated therefor by any funds remaining in the Maintenance Escrow. If Lessee was grossly negligent or reckless, Lessee shall be obligated to pay Lessor for the out-of-pocket expenses Lessor (or DVI) incurs in bringing such Equipment up to the status of such repair and working order as the Equipment would have had but for Lessee's gross negligence or recklessness, but not in excess of the Casualty Value for such Equipment 2.4 TAXES. Lessor shall pay, and hereby indemnifies Lessee on a net, after-tax basis, against, and shall hold it harmless from, all license fees, assessments, and sales, use, property, excise and other taxes and charges, other than those measured by Lessee's net income, now and hereafter imposed by any Governmental Authority upon or with respect to any of the Equipment, or the possession, ownership, use or operation thereof, or any Lease, or the consummation of the transactions contemplated by any Lease. Lessor shall file personal property tax returns, and shall pay personal property taxes payable with respect to the Equipment. 2.5 LOSS OF EQUIPMENT. Lessor assumes the risk that any item of Equipment becomes lost, stolen, damaged, destroyed or otherwise unfit or unavailable for use from any cause whatsoever other than Lessee's gross negligence or recklessness (an "EVENT OF LOSS"). So long as an item of Equipment is unavailable to Lessee due to an Event of Loss, Lessee shall have no liability to Lessor or DVI to pay Rent therefor. However, should any insurance be payable on account of such Event of Loss, then Lessee shall be entitled to receive or retain from such insurance proceeds an amount equal to what is necessary for Lessee to lease replacement Equipment, less any Rent payable, for the remainder of the Term and DVI, shall receive the remainder. 3. <Page> 2.6 INSURANCE. Lessor shall retain for the Lease Term at its own expense, property damage and liability insurance and insurance against loss or damage to the Equipment as a result of fire, explosion, theft, vandalism and such other risks of loss as are normally maintained on equipment of the type leased hereunder by companies carrying on the business in which Lessee is engaged, in such amounts, in such form and with such insurers as shall be satisfactory to Lessee (and DVI) and Lessee shall reimburse Lessor for the pro rated cost for each month a System remains subject to this Lease. In other words, should Lessee return a System as described in Paragraph 1.5, the obligation to reimburse Lessor for the insurance attributable to the individual returned System shall cease.

NON-USE AND NON-DISCLOSURE.

It is agreed that any derivative, modification or elaboration of any Confidential Information by any third party remains the proprietary property of the Company for purposes of this Agreement. Mr. Mandler and the Company each hereby covenants and agrees that, as between them, all Confidential Information acquired by the Company constitutes important, material and confidential and/or proprietary information of the Business, constitutes unique and valuable information, and affects the successful conduct of the Business and the Company's goodwill, and that the Company shall be entitled to recover its damages, in addition to any injunctive remedy that may be available, for any breach of this SECTION 2. c.

DIGIRAD IMAGING SYSTEMS, INC. a Delaware corporation By: --------------------------------------- Name: --------------------------------------- Title: --------------------------------------- ----------------------------------------------- JEFFREY MANDLER [SIGNATURE PAGE TO THE JEFFERY MANDLER NON-COMPETITION AND NON-DISCLOSURE AGREEMENT] 7. <Page> EXHIBIT F OMITTED <Page> EXHIBIT G INDEMNITY AGREEMENT THIS INDEMNITY AGREEMENT is executed as of this 29th day of September, 2000 by JEFFREY MANDLER ("Mandler") in favor of Digirad Imaging Systems, Inc. and its affiliates (including, without limitation, Digirad Corporation) as a material inducement to Digirad Imaging Systems, Inc. ("DIS") to enter into and perform that certain Asset Purchase Agreement (the "A/P Agreement") between DIS, Cardiovascualar Concepts, P.C. ("CVC") and Nuclear Imaging Services, Inc. ("NIS" and together with CVC, referred to as the "Company") and dated on or about the date hereof. Capitalized terms not otherwise defined herein shall have the meanings assigned to them in the A/P Agreement. 1. INDEMNIFICATION. Mandler hereby agrees that he shall indemnify, defend and hold harmless DIS and Digirad Corporation and their respective officers, directors, employees, agents, successors and assigns (collectively the "Indemnitees") from and against any and all costs, losses, Liabilities, damages, lawsuits, deficiencies, claims and expenses, including without limitation, interest, penalties, costs of mitigation, clean-up or remedial action, attorneys' fees and all amounts paid to third parties in investigation, defense or settlement of any of the foregoing (collectively, the "Damages"), suffered by any of the Indemnitees, incurred in connection with, arising out of, resulting from or incident to: (a) any breach of any covenant, representation, warranty or agreement or the inaccuracy of any representation, made by NIS, CVC, Mandler, or any of their respective employees, agents or representatives in or pursuant to the A/P Agreement or the other Acquisition Documents; (b) the filing of a petition under title 11 of the United States Code (the "Bankruptcy Code") by or against Medical Management Concepts, Inc. ("MMC") to the extent such Damages could have been avoided or reduced by any Indemnitee if MMC had entered into the agreements that MMC entered into with any of DIS, Digirad Corporation, or any of their affiliates on or about the date hereof (the "Subject Agreements") AFTER such petition of MMC was filed rather than before, including without limitation, any fees, costs or losses or other Damages incurred by and Indemnitee (i) in defending their respective rights in such ensuing bankruptcy of MMC, (ii) in paying, whether voluntarily or involuntarily, due to practical, legal or business need or expedience, any debts or obligations of MMC that could have been compromised or discharged if MMC had filed bankruptcy before the Subject Agreements were entered into, or (iii) in protecting its rights against third parties where the bankruptcy court's approval (upheld on appeal, if any) of the Subject Agreements could have eliminated or reduced such Damages. 2. PROCEDURE. Should any Indemnitee desire to assert a claim for indemnification, such Indemnitee shall, if it is not DIS or Digirad Corporation, first give notice of the claim to either DIS or Digirad Corporation. If DIS or Digirad Corporation does not oppose assertion of the claim by the Indemnitee, either DIS or Digirad shall provide written notice to Mandler of the claim (the "Claim Notice"). Upon receipt of a Claim Notice, Mandler 1 <Page> shall have ten (10) days to object, in writing, to such claim (the "Dispute Notice"), providing notice thereof to the party asserting the claim and, if different, to DIS and Digirad Corporation. If the claim is not timely disputed by Mandler, the Indemnitee asserting a right to indemnification shall have the right to enforce its indemnity rights as defined hereunder. If Mandler timely provides a Dispute Notice, Mandler and the party or parties asserting the indemnification claim and DIS and Digirad Corporation (if they choose to participate in the resolution of the dispute) shall attempt in good faith to agree upon the rights or the respective parties with respect to such claim. If the parties agree as to the resolution of such claim, they shall prepare a memorandum setting forth the terms of such resolution and signed by each party. If no agreement is reached with thirty (30) days after delivery of the Dispute Notice, any of Mandler, the Indemnitee seeking indemnification, DIS or Digirad Corporation may demand arbitration of the matter and the matter shall be settled by arbitration conducted in accordance with this Agreement. The decision of the arbitrators as to the validity and amount of any claim shall be final, binding and conclusive upon the parties to the arbitration. 3. DEFENSE OF CLAIMS. If any Action or Proceeding is filed or initiated against any Indemnitee, written notice thereof shall be given to Mandler (and, if different, to DIS and Digirad Corporation) as promptly as practicable (and in any event within ten (10) days after the service of the citation or summons); provided, however, that the failure of any Indemnitee to give timely notice to Mandler shall not affect rights to indemnification hereunder except to the extent that Mandler has been materially prejudiced by such failure to give timely notice, and the failure of the Indemnitee to give either DIS or Digirad Corporation notice shall (a) oblige Mandler to notify DIS and Digirad (if they are not the Indemnitee notifying Mandler of the Action or Proceeding), and (b) the 15 day period referred to below within which Mandler must assume the defense of the Action or Proceeding shall be extended to 25 days if and only if prior to the 15th day, Mandler has given notice to DIS and Digirad Corporation where the Indemnitee has failed to do so. After such notice, if Mandler shall acknowledge in writing to the Indemnitee providing notice to Mandler that Mandler shall be obligated under the terms of his indemnity hereunder in connection with such Action or Proceeding, then Mandler shall be entitled, if he so elects, to take control of the defense and investigation of such Action or Proceeding and to employ and engage attorneys of his own choice to handle and defend the same, such attorneys to be reasonably satisfactory to the Indemnitee giving notice of the Action or Proceeding (and, if different, to DIS and Digirad Corporation), at Mandler's cost, risk and expense (unless (i) Mandler has failed to assume the defense of such Action or Proceeding or (ii) the named parties to such Action or Proceeding include both Mandler and the subject Indemnitee, and such Indemnitee and its counsel determine in good faith that there may be one or more legal defenses available to such Indemnitee that are different from or additional to those available to Mandler and that joint representation would be inappropriate), and to compromise or settle such Action or Proceeding, which compromise or settlement shall be made only with the written consent of the subject Indemnitee (and, if different, DIS and Digirad Corporation), such consent not to be unreasonably withheld. The subject Indemnitee (and, if different, DIS and Digirad Corporation) may withhold such consent if such compromise or settlement would materially adversely affect the conduct of the business of any of the subject Indemnitee, DIS and/or Digirad Corporation. Notwithstanding the foregoing, the subject Indemnitee (and, if different, DIS and Digirad Corporation) may not withhold consent if such compromise or settlement includes an unconditional release of claims against the subject Indemnitee (and, if different, DIS and Digirad Corporation). If (i) Mandler fails to assume the defense of such Action or Proceeding within 2. <Page> fifteen (15) days after receipt of notice thereof pursuant to this Agreement, or (ii) the named parties to such Action or Proceeding include both Mandler and the subject Indemnitee and the subject Indemnitee and his, her or its counsel determine in good faith that there may be one or more legal defenses available to such Indemnitee that are different from or additional to those available to Mandler and that joint representation would be inappropriate, the subject Indemnitee against which such Action or Proceeding has been filed or initiated will (upon delivering notice to such effect to Mandler) have the right to undertake, at Mandler's cost and expense, the defense, compromise or settlement of such Action or Proceeding on behalf of and for the account and risk of Mandler; provided, however, that such Action or Proceeding shall not be compromised or settled without the written consent of Mandler, which consent shall not be unreasonably withheld. In the event the subject Indemnitee assumes defense of the Action or Proceeding, such Indemnitee will keep Mandler reasonably informed of the progress of any such defense, compromise or settlement and will consult with, when appropriate, and consider any reasonable advice from, Mandler of any such defense, compromise or settlement. 4. LIABILITY. Mandler shall be liable for any settlement of any action effected pursuant to and in accordance with this Agreement and for any final judgment (subject to any right of appeal), and Mandler agrees to indemnify and hold harmless the subject Indemnitee (and all Indemnitees) from and against any Damages by reason of such settlement or judgment. Furthermore, regardless of whether Mandler or any given Indemnitee takes up the defense, Mandler will pay reasonable costs and expenses in connection with the defense, compromise or settlement for any Action or Proceeding under this Agreement. 5. COOPERATION. Each Indemnitee shall cooperate in all reasonable respects with Mandler and his attorneys in the investigation, trial and defense of any Action or Proceeding and any appeal arising therefrom; provided, however, that any Indemnitee that is named in such Action or Proceeding, and DIS and Digirad Corporation may, at its own cost, participate in the investigation, trial and defense of such Action or Proceeding and any appeal arising therefrom. Mandler shall pay all expenses due under this Agreement as such expenses become due. 6. SECURITY. As collateral for and to secure (a) the payment and performance of Mandler under this Agreement, and (b) any and all obligations Mandler may have or acquire under the A/P Agreement and the other Acquisition Documents, Mandler hereby grants to DIS and Digirad Corporation a security interest (which shall be of no less than first priority) in all presently owned or hereafter acquired capital stock of Mandler in either DIS or Digirad Corporation, together with all dividends and distributions received at any time by Mandler on account of such capital stock, and together with whatever may be received by Mandler on account of said capital stock (whether cash, additional stock, or other personal property of any kind), together with all proceeds of any of the foregoing. In addition, Mandler covenants and agrees to execute and deliver to DIS and Digirad Corporation such further and additional documentation as either DIS or Digirad Corporation may reasonably request to provide DIS and Digirad a duly perfected, first priority security interest in all such collateral described in this Section 6. 3. <Page> Executed as of this ___ day of _________, September, 2000. --------------------------------------- JEFFERY MANDLER 4. <Page> EXHIBIT H CERTIFICATE OF THE SECRETARY OF THE EACH COMPANY CERTIFICATE OF NUCLEAR IMAGING SYSTEMS, INC.

BY: ------------------------------------------------ NAME: --------------------------------------------- TITLE: -------------------------------------------- --------------------------------------------------- JEFFREY MANDLER 10 <Page> EXHIBIT A DESCRIPTION OF SERVICES MMC shall provide, in addition to any additional services agreed upon by the parties from time to time or reasonably necessary to effectuate the Services set forth below: CATEGORY 1: BILLING AND COLLECTION SERVICES. MMC shall provide the Company with Medical Billing and Collection Services as described in this Agreement, and (a) any other services as may be reasonably requested from time to time by the Company relating to such Medical Billing and Collection Services , and (b) any other services which may be necessary to performing Medical Billing and Collection Services.

Among the Services that fall within this Category 2 are the Services listed in Sections 2.7, 2.10, 2.11 and 2.14 of the Agreement. <Page> EXHIBIT B PAYMENT FOR SERVICES In consideration of the two categories of Services provided to the Company by MMC as identified in Exhibit A, the Company shall pay MMC, on a monthly basis the following: FOR BILLING AND COLLECTIONS SERVICES (CATEGORY 1): The Company shall pay to MMC a fee equal to five percent (5%) of "Estimated Net Revenue" as that term is defined below, which Estimated Net Revenue figure is subject to adjustment as set forth below. FOR SALES, MARKETING AND OPERATIONS SERVICES (CATEGORY 2): So long as the Sales Services Initial Term (or any month to month extensions thereof) is in effect, the Company shall pay MMC as and when set forth in Section 1.3 of the Agreement, a fee equal to twelve and one-half percent (12.5%) of the "Estimated Net Revenue" (as that term is defined below) attributable to the applicable month for which payment is due, which Estimated Net Revenue figure is subject to adjustment as set forth below. ADJUSTMENT OF PAYMENTS DUE TO ACTUAL COLLECTIONS: Sixty days after the end of each calendar quarter, the Estimated Net Revenue figures calculated for each month during that quarter will be reviewed and compared to the actual collections on account of the billings made during the months in such quarter. If the payments to MMC over the course of the quarter (in the aggregate) for either category of Services was too low (an "Underpayment") because the Estimated Net Revenue figure in each of the three month in the quarter was less than the actual collections received on account of billings generated in those months, then the Company shall pay to MMC the amount of the Underpayment within the next 15 days (unless there remains outstanding some portion of the prepayment provided for in Section 1.3, in which case the Underpayment amount will be set off to reduce the pre-payment balance). If the payment to MMC based on the Net Estimated Revenue figures during the course of the quarter was too high (an "Overpayment"), then the Overpayment amount shall be deducted from any sums otherwise due or coming due from the Company to MMC or, if none (such as, for example, because the Term of the Agreement has ended) upon demand by the Company. If after the conclusion of the 60 day period referred to above, there remains any uncollected sums, MMC shall continue to maintain the records for these accounts and when and if any such accounts ("Delinquents Accounts") are collected by MMC, MMC shall be entitled to receive (unless the Company is entitled to an offset of some type) 12.5% of the amount actually collected if MMC is still providing Sales Marketing and Operations Services, and 5% of the amount actually collected if MMC is still providing Billing and Collections Services. In the event a third party other than MMC has collected these sums, the amount payable to the third party shall be deducted from sums otherwise payable to MMC. <Page> ADJUSTMENTS DUE TO OPEN TERRITORIES. Should there be a sales territory for which a sales representative is currently responsible that is later vacated for a period longer than 30 days (an "Open Direct Sales Territory"), payment in accordance with the foregoing formula will be reduced in an amount equal to the salary and benefits that would have been payable to such a representative pro rated for the full amount of time (including the 30-day period that triggered this remedy) that the territory is "open." Should MMC fill the vacant position, MMC must give notice to the Company of the replacement and if the Company has not obtained substitute coverage for the territory, the payments to MMC will return to the formula set forth above. DEFINITIONS: "ESTIMATED NET REVENUE" means an estimation performed on or immediately following the end of any given calendar month of the net revenue generated during such month then ending determined by calculating the gross sums billed to customers of the Mobile Business by MMC for that particular month in the "Applicable Markets" defined below, less "Contract Allowances" (defined below) and "Bad Debt Losses" (as defined below) as determined from time to time for the particular month.

"CONTRACT ALLOWANCES" means an amount based on a percentage agreed upon by MMC and the Company and based on MMC's historical performance by which gross billings are to be reduced due to discounts and contractual reductions. Contract Allowances may be adjusted monthly based on MMC's historical performance. "BAD DEBT ALLOWANCES" means an amount based on a percentage agreed upon by MMC and the Company and based on MMC's historical experience by which gross billings are to be reduced due to poor payment history or creditworthiness of customers. Bad Debt Allowances may be adjusted monthly based on MMC's historical experience and the customer mix. <Page> EXHIBIT C EMPLOYEE LEASE EMPLOYEE LEASE AGREEMENT This EMPLOYEE LEASE AGREEMENT is made and entered into as of this 29th day of September, 2000 by and between Digirad Imaging Systems, Inc., a Delaware corporation, with its principal offices located at 9350 Trade Place, San Diego CA 92126-6334 (hereinafter referred to as "CLIENT") and Medical Management Concepts, Inc., a Pennsylvania corporation having its principal offices located at The Mark Building, 3223 Phoenixville Pike, Suite C, Caller Box 4002, Malvern, PA 19355 (hereinafter referred to as "MMC.")

All Proprietary Information and all title, patents, patent rights, copyrights, mask work rights, trade secret rights, and other intellectual property and rights anywhere in the world (collectively "Rights") in connection therewith shall be the sole property of the Company. Consultant hereby assigns to the Company any Rights Consultant may have or acquire in such Proprietary Information. At all times, both during the term of this Agreement and after its termination, Consultant will keep in confidence and trust and will not use or disclose any Proprietary Information or anything relating to it without the prior written consent of an officer of the Company. Consultant acknowledges that any disclosure or unauthorized use of Proprietary Information will constitute a material breach of this Agreement and cause substantial harm to the Company for which damages would not be a fully adequate remedy, and, therefore, in the event of any such breach, in addition to other available remedies, the Company shall have the right (without posting any bond or other security) to obtain temporary, preliminary and/or permanent injunctive relief. d. All Company Materials shall be the sole property of the Company.

Consultant hereby irrevocably designates and appoints the Company and its duly authorized officers and agents, as Consultant's agents and attorneys-in-fact to act for and in behalf and instead of Consultant, to execute and file any documents and to do all other lawfully permitted acts to further the above purposes with the same legal force and effect as if executed by Consultant. <Page> f. Consultant represents that performance of all the terms of this Agreement will not breach any agreement to keep in confidence proprietary information acquired by Consultant in confidence or in trust prior to the execution of this Agreement. Consultant has not entered into, and Consultant agrees not to enter into, any agreement either written or oral that conflicts or might conflict with Consultant's performance of the Services under this Agreement. 7. NON-COMPETITION. In addition to the obligations of Consultant under the Non-Competition Agreement, and not in lieu thereof, Consultant agrees that commencing on the execution of this Agreement and continuing until three years after the Consultation Period, Consultant will not, without the express written permission of Company, as an employee, agent, consultant, advisor, independent contractor, general partner, officer, director, stockholder, investor, lender or guarantor of any corporation, partnership or other entity, or in any other capacity directly or indirectly: a. Participate or engage in the design, development, manufacturing, production, marketing, sale or servicing of any product, or the provision of any service, that directly relates to Mobile Nuclear Imaging Services (the "Business") in the United States or in any country in the world; b. Induce or attempt to induce any person who at the time of such inducement is an employee of the Company or the Company's subsidiaries to perform work or services for any other person or entity other than the Company or its subsidiaries; c. Induce or attempt to induce any customer or client of either the Company or NIS to cease doing business with the Company or to switch some or all of their business from Company to another provider of services similar to those provided by the Company, or d. Permit the name of Consultant to be used in connection with a competitive Business. Notwithstanding the foregoing, Consultant will not be prohibited from competing with the Company in the United States or another country, if the Company or its affiliates, or any entity deriving title to their good will or capital stock, ceases to carry on a like Business therein; provided, however, that this exception to Consultant's covenant not to compete only applies to the state or country in which the Business of the Company was previously but is no longer carried on and does not affect the enforceability of this Paragraph in the states or countries in which the Business is continued. As partial consideration for the foregoing provisions of this Section 7, the Company agrees that so long as Consultant does not breach any provision of this Section 7 (or otherwise materially breach this Agreement or the Non-Competition Agreement), Consultant's entitlement to receive the stock referred to in Section 5 shall be subject to a minimum distribution of 100,000 shares which, if not previously distributed to Consultant, shall be distributed at the conclusion of the 3 years during which Consultant is not permitted to compete as described in this Section 7. <Page> 8. SAVINGS CLAUSE. If any restriction set forth in Section 7 above is held to be unreasonable, then Consultant agrees, and hereby submits, to the reduction and limitation of such prohibition to such area or period as shall be deemed reasonable. Consultant agrees that during the period Consultant renders services to the Company, Consultant will not engage in any employment, business, or activity that is in any way competitive with the Mobile Business of the Company (or natural or likely expansions thereof), and Consultant will not assist any other person or organization in competing with the Company or in preparing to engage in competition with the Mobile Business of the Company (or natural or likely expansions thereof). 9. INJUNCTIVE RELIEF. Consultant expressly agrees that the covenants set forth in Sections 7(a) and 7(c) are reasonable and necessary to protect the Company and its legitimate business interests, and to prevent the unauthorized dissemination of confidential Information to competitors of the Company. Consultant also agrees that the Company will be irreparably harmed and that damages alone cannot adequately compensate the Company if there is a violation of Sections 6 or 7 by Consultant, and that injunctive relief against Consultant is essential for the protection of the Company. Therefore, in the event of any such breach, it is agreed that, in addition to any other remedies available, the Company shall be entitled as a matter of right to injunctive relief in any court of competent jurisdiction, plus attorneys' fees actually incurred for the securing of such relief. 10. TERMINATION OF CONSULTING PERIOD. As noted above, the Consulting Period shall end at the end of the Initial Period plus each Subsequent Period as becomes effective, unless the period is terminated sooner under this Section 10. The Consulting period may be terminated prior to the conclusion of the Initial Period or any ensuing Subsequent Period as and when set forth below: a.
