During the period commencing on the Original Issue Date and terminating on the Maturity Date, interest on the unpaid principal amount of this Note shall accrue at a rate equal to 7 3/4% per annum, compounded monthly, computed on the basis of actual days elapsed over a 360-day year, and shall be payable monthly (commencing on February 28, 2005 and thereafter on the 28th of each month) in cash up to and including the Maturity Date, subject to a ten (10) day grace period; provided that if a required interest payment is not paid within such ten (10) day grace period, interest shall be compounded from the date that such interest was due and payable without regard to such grace period.

(b) Principal. The principal balance outstanding on this Note, and any accrued and unpaid interest thereon, shall be due and payable to the Holder on February 28, 2012 (the “Maturity Date”). Contemporaneously with the repayment of this Note, the Holder shall surrender this Note, duly endorsed, at the office of the Company.

(c) Payments. All payments of principal, interest, fees and other amounts due hereunder shall be made by the Issuers in lawful money of the United States of America by wire transfer or by any other method approved in advance by the Holder to the account of the Holder at the address of the Holder set forth in Section 10 hereof or at such other place designated by the Holder in writing to the Company.

(d) Acceleration of the Maturity Date. Notwithstanding anything to the contrary contained herein, this Note and all other Obligations shall become due and payable together with all accrued interest due on the outstanding principal amount hereunder, at the option of the Holders of at least 25% of the principal amount and interest outstanding exercised, by written notice to the Company, in the case of clauses (i) to (viii) below and without notice or any other action by such Holders in the case of clauses (ix) or (x) below, in the event (each an “Event of Default”) that (i) the Issuers fail to pay the principal of or interest on this Note as and when due, subject to a ten (10) day grace period; (ii) any of the Issuers or their Subsidiaries shall default in the performance of or otherwise breach any of its representations and warranties, covenants or other obligations set forth in this Note, the Purchase Agreement or any of the Notes Documents, and if such default is capable of cure, such default remains uncured beyond any applicable cure period; provided that with respect to any breach or default of the covenants in Section 6, there shall be a fifteen (15) calendar day cure period (to the extent such breach or default is capable of cure) commencing from the earlier of (i) receipt by the Company of written notice of such breach or default from the Holder and (ii) the time at which an authorized officer of the Company or any Subsidiary knew or became aware of such breach or default; provided further that with respect to the covenant set forth in Sections 6(a) there shall be no cure period with respect to any breach or default that adversely affects the Holder; (iii) the Collateral Agent (on behalf of the Holders) shall not have the right to enforce its remedies under Section 4 of this Note or under any Subsidiary Security Agreement; (iv) the Holder shall not have a perfected security interest in the Collateral pursuant to the terms set forth herein or in any Subsidiary Security Agreement other than Holder’s action or inaction; (v) the Company fails when required to remove any restrictive legend of any certificate relating to Conversion Shares, Redemption

Warrants, Waiver Warrants or any other securities issuable in accordance with the terms of the Notes or the exercise or conversion of the Redemption Warrants, Waiver Warrants or any other convertible securities issuable in accordance with the terms of the Notes, issued to the Holders, and any such failure continues uncured for ten (10) Business Days after the Company has been notified of such failure in writing by the Holder; (vi) the Issuers or any of their Subsidiaries fail to pay, when due, or within any applicable grace period, any payment with respect to any Indebtedness of the Issuers or their Subsidiaries having an outstanding principal amount in excess of $250,000 (including, without limitation, any of the Other Notes), or otherwise is in breach or violation of any agreement for Indebtedness in an amount in excess of $250,000 which breach or violation permits the other party thereto to declare a default or otherwise accelerate amounts due thereunder and which breach or violation is not waived or otherwise cured hereunder or under the documents evidencing such Indebtedness, including, without limitation, by exercise of the RGGPLS Cure or ComVest Cure, as applicable, pursuant to Section 6(e); (vii) the entry of a final judgment against any of the Issuers or their Subsidiaries not covered by insurance of a financially sound and reputable insurer that has not declined coverage, which is not subject to appeal by the Issuers or their Subsidiaries and is not satisfied, stayed, vacated or discharged of record within thirty (30) calendar days of being entered, in an amount in excess of $250,000, or the attachment or seizure of or levy upon any property of the Issuers or their Subsidiaries valued in excess of $250,000 to satisfy an obligation of the Issuers or their Subsidiaries; (viii) the Company provides notice to any Holder of the Notes, including by way of public announcement, at any time, of its intention not to issue, or otherwise refuses to issue, Conversion Shares to any Holder of the Note upon conversion in accordance with the terms of the Notes or shares of Common Stock upon exercise of the Waiver Warrants; (ix) any of the Issuers or their Subsidiaries shall file a petition under bankruptcy, insolvency or debtor’s relief Law or make an assignment for the benefit of its creditors or (x) proceedings shall be instituted against any of the Issuers or their Subsidiaries before a court of competent jurisdiction under any federal or state bankruptcy Law that (X) is for relief against the Issuers or their Subsidiaries in an involuntary case brought with respect to the Issuers or their Subsidiaries in such court, (Y) seeks to appoint a custodian, receiver or other similar official for all or substantially all the Issuers’ property or of their Subsidiaries or (Z) seeks to liquidate the Issuers of their Subsidiaries, and such proceedings remain unstayed and in effect for sixty (60) days. In the event that the Obligations hereunder are accelerated pursuant to this Section 2(d), interest shall continue to accrue at 10 3/4% per annum as of the date of such acceleration until such date as the Holder is paid in full under this Note.

3. Conversion.

(a) Conversion at the Option of the Holder. The Holder may, at any time and from time to time on or after the Original Issue Date, convert all or any part of the outstanding principal amount of this Note, plus all accrued interest thereon through the Conversion Date, into a number of fully paid and nonassessable shares of Common Stock (“Conversion Shares”) upon surrender of the Note. The number of shares of Common Stock issuable upon surrender of the Note shall be determined in accordance with the following formula:

Conversion Amount
Conversion Price

(b) Mechanics of Conversion. In order to effect a conversion pursuant to this Section 3, the Holder shall: (a) fax (or otherwise deliver) a copy of the fully executed Notice of Conversion to the Company and (b) surrender or cause to be surrendered this Note, duly endorsed, along with a copy of the Notice of Conversion as soon as practicable thereafter to the Company. Upon receipt by the Company of a facsimile copy of a Notice of Conversion from a Holder, the Company shall within two (2) business days send, via facsimile, a confirmation to such Holder stating that the Notice of Conversion has been received, advising the Holder of any additional documentation required by the transfer agent for the Common Stock to issue the Conversion Shares in the manner provided in the Notice of Conversion (the “Additional Documentation”) and the name and telephone number of a contact person at the Company regarding the conversion. The Company shall not be obligated to issue Conversion Shares upon a conversion unless either this Note is delivered to the Company as provided above, or the Holder notifies the Company that such certificates have been lost, stolen or destroyed and delivers the documentation to the Company required by Section 13. Such conversion shall be deemed to have been made effective as of the Conversion Date and the rights of the Holder of the Notes being converted shall cease as of the Conversion Date except for the rights to receive Conversion Shares, and the Person entitled to receive the Conversion Shares shall be treated for all purposes as having become the record holder of such Conversion Shares at such time and shall have all the rights and privileges of a holder of Common Stock with respect to such Conversion Shares.

(c) Delivery of Conversion Shares Upon Conversion. Upon the surrender of this Note accompanied by a Notice of Conversion and any Additional Documentation, the Company shall, no later than the later of (a) the second Business Day following the Conversion Date and (b) the third Business Day following the date of such surrender (or, in the case of lost, stolen or destroyed certificates, after provision of indemnity pursuant to Section 13) (the “Delivery Period”), issue and deliver to the Holder or its nominee (x) that number of Conversion Shares issuable upon conversion of the portion of this Note being converted and (y) a new Note in the form hereof representing the balance of the principal amount hereof not being converted, if any. If the Company’s transfer agent is participating in the Depositary Trust Company (“DTC”) Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend and the Holder thereof is not then required to return such certificate for the placement of a legend thereon, the Company shall cause its transfer agent to electronically transmit the Conversion Shares to the Holder by crediting the account of the Holder or its nominee with DTC, as specified in the Notice of Conversion, through its DTC Deposit Withdrawal Agent Commission System (“DTC Transfer”). If the aforementioned conditions to a DTC Transfer are not satisfied, the Company shall deliver to the Holder physical certificates representing the Conversion Shares. Further, the Holder may instruct the Company to deliver to the Holder physical certificates representing the Conversion Shares in lieu of delivering such shares by way of DTC Transfer.

(d) Adjustment to Conversion Price. The Conversion Price in effect at any time shall be subject to adjustment from time to time upon the happening of certain events, as follows:

(i) Common Stock Dividends; Common Stock Splits; Reverse Common Stock Splits. If the Company, at any time while this Note is outstanding, (A) shall pay a stock dividend on its Common Stock, (B) subdivide outstanding shares of Common Stock into a larger number of shares, or (C) combine outstanding shares of Common Stock into a smaller number of shares, the Conversion Price shall be multiplied by a fraction the numerator of which shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and the denominator of which shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section 3(d)(i) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(ii) Subscription Rights. If the Company, at any time while this Note is outstanding, shall fix a record date for the distribution to all of the holders of Common Stock evidence of its indebtedness or assets or rights, options, warrants or other securities entitling them to subscribe for, purchase, convert to, exchange for or to otherwise acquire any security (excluding those referred to in Section 3(d)(i) above), then in each such case the Conversion Price at which this Note shall thereafter be exercisable shall be determined by multiplying the Conversion Price in effect immediately prior to the record date fixed for determination of shareholders entitled to receive such distribution by a fraction, the denominator of which shall be the average Daily Market Price of the Common Stock for the ten (10) Trading Days prior to the record date mentioned above, and the numerator of which shall be such average Daily Market Price of the Common Stock for the ten (10) Trading Days prior to such record date less the then fair market value at such record date of the portion of such evidence of indebtedness or assets or rights, options, warrants or other securities so distributed applicable to one outstanding share of Common Stock as determined by the Board of Directors in good faith; provided, however, that in the event of a distribution exceeding twenty percent (20%) of the net assets of the Issuers, such fair market value shall be determined by an appraiser selected by the Holders of a majority of the principal amount and interest of the Notes outstanding and reasonably acceptable to the Company. The Company shall pay for all such appraisals. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

(iii) Other Events. In case of (A) any reclassification of the Common Stock into other securities of the Company, (B) any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property or (C) any merger or consolidation with or into any persons, or any sale or other disposition of all or substantially all of the assets of the Issuers to any person (each of (A), (B) or (C), an “Extraordinary Event”), the Holder shall have the right thereafter to convert this Note into shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Stock following such Extraordinary Event, that the Holder would have been entitled to receive had it converted this Note immediately prior to such Extraordinary Event (without taking into account any limitations or restrictions on the convertibility of the Notes). In the case of an Extraordinary Event, the terms of any such Extraordinary Event shall include such terms so as to continue to give to the Holder the right to receive the securities, cash or property set forth in this Section 3(d)(iii) upon any conversion following such Extraordinary Event. This provision shall similarly apply to successive Extraordinary Events. For the avoidance of doubt, nothing

contained in this clause (iii) shall be construed to impair the Issuers’ or Holders’ rights under Section 5, including, without limitation, under Section 5(b).

(iv) Partial Redemption of Notes Pursuant to Section 5(c). Upon the happening of a partial redemption of the Note pursuant to Section 5(c), the Conversion Price in effect immediately prior to such redemption shall be reduced to the price determined by multiplying the Conversion Price, in effect immediately prior to the redemption, by a fraction, the numerator of which shall be the principal amount of the Note outstanding immediately after the partial redemption and the denominator of which shall be the principal amount of the Note immediately prior to the partial redemption.

(v) No Impairment. If any event shall occur as to which the provisions of this Section 3(d) are not strictly applicable but the failure to make any adjustment would adversely affect the conversion rights under the Notes in accordance with the essential intent and principles of such Section, then, in each such case, the Conversion Price of the Notes shall be adjusted in such manner as the Board of Directors of the Company shall in good faith determine to be equitable under the circumstances; provided, however, that no adjustment to the Conversion Price shall be made under this clause (v) as a result of any bona fide sale of the Company’s Capital Stock to a third party.

The Issuers will not, by amendment of their organizational documents or through any consolidation, merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holders hereunder against dilution of the type contemplated by the provisions of this Section 3(d) or other impairment.

(e) Record Date. In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be, provided, however, that any such adjustment in the Conversion Price shall be reversed or shall not become effective, as applicable, if the Company abandons the action to which the record date pertains.

(f) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company or any of its wholly-owned Subsidiaries, and the disposition of any such shares (other than the cancellation or retirement thereof) shall be considered an issue or sale of Common Stock for the purpose of Section 5(d).

(g) Fractional Shares. Upon a conversion hereunder, the Company shall not be required to issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a

share based on the closing bid price at such time. If the Company elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

(h) Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to Section 3, the Company, at its own expense, shall promptly compute such adjustment or readjustment and prepare and furnish to each Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon conversion of the Note.

4. Security; Remedies. Unless otherwise defined in this Note, each of the defined terms used in this Section 4 shall have the meanings ascribed to them in the Credit Agreement as of the date hereof.

(a) To secure the prompt payment or performance in full when due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise, of all the Obligations, each Issuer hereby grants and each Initial Issuer hereby confirms and continues to grant to the Collateral Agent (for the benefit of the Holders) a continuing security interest in and Lien upon, and pledges to the Collateral Agent (for the benefit of the Holders), all of its right, title and interest in and to the following Collateral, which security interest is intended to be a security interest, which is subordinate to any Liens securing Senior Indebtedness permitted to be incurred pursuant to Section 6(c):

(i) all of such Issuer’s tangible personal property, including without limitation all present and future Inventory and Equipment (including items of equipment which are or become Fixtures), now owned or hereafter acquired;

(ii) all of such Issuer’s intangible personal property, including without limitation all present and future Accounts, Contract rights, Permits, General Intangibles, Chattel Paper, Documents, Instruments, Deposit Accounts, Investment Property, Letter-of-Credit Rights, Supporting Obligations, rights to the payment of money or other forms of consideration of any kind, tax refunds, insurance proceeds, now owned or hereafter acquired, and all intangible and tangible personal property relating to or arising out of any of the foregoing;

(iii) all of such Issuer’s present and future Government Contracts and rights thereunder and the related Government Accounts and proceeds thereof, now or hereafter owned or acquired by such Issuer; provided, however, that the Holder shall not have a security interest in any rights under any Government Contract of such Issuer or in the related Government Account where the taking of such security interest is a violation of an express prohibition contained in the Government Contract (for purposes of this limitation, the fact that a Government Contract is subject to, or otherwise refers to, Title 31, § 203 or Title 41, § 15 of the United States Code shall not be deemed an express prohibition against assignment thereof) or is prohibited by applicable Law, unless in any case consent is otherwise validly obtained; and

(iv) any and all additions and accessions to any of the foregoing, and any and all replacements, products and proceeds (including insurance proceeds) of any of the foregoing.

(b) Notwithstanding the foregoing provisions of this Section 4, such grant of a security interest shall not extend to, and the term “Collateral” shall not include, any General Intangibles of Issuers to the extent that (i) such General Intangibles are not assignable or capable of being encumbered as a matter of Law or under the terms of any license or other agreement applicable thereto (but solely to the extent that any such restriction shall be enforceable under applicable Law) without the consent of the licensor thereof or other applicable party thereto, and (ii) such consent has not been obtained; provided, however, that the foregoing grant of a security interest shall extend to, and the term “Collateral” shall include, each of the following: (a) any General Intangible which is in the nature of an Account or a right to the payment of money or a proceed of, or otherwise related to the enforcement or collection of, any Account or right to the payment of money, or goods which are the subject of any Account or right to the payment of money, (b) any and all proceeds of any General Intangible that is otherwise excluded to the extent that the assignment, pledge or encumbrance of such proceeds is not so restricted, and (c) upon obtaining the consent of any such licensor or other applicable party with respect to any such otherwise excluded General Intangible, such General Intangible as well as any and all proceeds thereof that might theretofore have been excluded from such grant of a security interest and from the term “Collateral.”

(i) Upon the execution and delivery of the Original Notes on the Original Issue Date, and upon the proper filing of the necessary financing statements, recordation of the Collateral Patent, Trademark and Copyright Assignment in the United States Patent and Trademark Office and/or the United States Copyright Office without any further action, the Holder had as of such date, and as of the date hereof upon the execution and delivery of the Notes will continue to have, a good, valid and perfected Lien and security interest in the Collateral of the Initial Issuers, which is subordinate only to any Liens securing Senior Indebtedness permitted to be incurred pursuant to Section 6(c) and subject to no transfer or other restrictions or Liens of any kind in favor of any other Person except for Permitted Liens. Upon the execution and delivery of this Note (and in the case of any future Subsidiary, upon the execution and delivery of the Subsidiary Guaranty and Subsidiary Security Agreement), and upon the proper filing of the necessary financing statements, recordation of the Collateral Patent, Trademark and Copyright Assignment in the United States Patent and Trademark Office and/or the United States Copyright Office without any further action, the Holder will have, a good, valid and perfected Lien and security interest in the Collateral of Diabetes and National (and any future Subsidiary that executes and delivers a Subsidiary Guaranty and Subsidiary Security Agreement), which is subordinate only to any Liens securing Senior Indebtedness permitted to be incurred pursuant to Section 6(c) and subject to no transfer or other restrictions or Liens of any kind in favor of any other Person except for Permitted Liens. Except as expressly permitted by the Notes, each Issuer owns its interests in the Collateral free and clear of any Liens and no financing statement relating to any of the Collateral is on file in any public office except those (i) on behalf of the Holders, (ii) in connection with Permitted Liens and/or (iii) those being terminated.

(ii) No Issuer (or predecessor by merger or otherwise of such Issuer), has within the five-year period preceding the date hereof, had a different name from the name of such Issuer listed on the signature pages hereof, except the names set forth on Schedule 4(c).

(iii) This Note shall create a continuing security interest in the Collateral and the security interest created herein shall (i) remain in full force and effect until the payment and performance in full of the Obligations, (ii) be binding upon Issuers and their respective successors and assigns, and (iii) inure, together with the rights and remedies of the Holders and the Collateral Agent hereunder, to the benefit of the Holders, the Collateral Agent and their successors, transferees and assigns.

(d) Collateral Administration.

(i) All Collateral (except Deposit Accounts) will at all times be kept by Issuer at the locations set forth on Schedule 4(d) and shall not, without thirty (30) calendar days prior written notice to the Collateral Agent, be moved therefrom unless the Collateral Agent has entered into the necessary documents to perfect and enforce its security interest therein at such new location, and in any case shall not be moved outside the continental United States.

(ii) Each Issuer shall keep accurate and complete records of its Accounts and all payments and collections thereon and shall submit such records to the Collateral Agent on such periodic basis as the Collateral Agent may request. Following the occurrence and during the continuance of an Event of Default, if requested by the Collateral Agent, such Issuer shall execute and deliver to the Collateral Agent formal written assignments (or, in the case of Medicaid/Medicare Account Debtors, documents necessary to comply with the Federal Assignment of Claims Act) of all of its Accounts weekly or daily as the Collateral Agent may request, including all Accounts created since the date of the last assignment, together with copies of claims, invoices and/or other information related thereto. To the extent that collections from such assigned accounts exceed the outstanding principal amount together with any accrued interest due on the Notes and all First Priority Lien Indebtedness, such excess amount shall not accrue interest in favor of such Issuer, but shall be available to such Issuer upon such Issuer’s written request.

(iii) Following an occurrence or during the continuance of an Event of Default, any of the Collateral Agent’s officers, employees, representatives or agents shall have the right, at any time during normal business hours, in the name of the Collateral Agent, any designee of the Collateral Agent or Issuers, to verify the validity, amount or any other matter relating to any Accounts or Inventory of Issuer. Issuers shall cooperate fully with the Collateral Agent in an effort to facilitate and promptly conclude such verification process.

(iv) To expedite collection, each Issuer shall endeavor in the first instance to make collection of its Accounts for the Collateral Agent. The Collateral Agent shall have the right at all times after the occurrence and during the continuance of an Event of Default to notify (a) Account Debtors owing Accounts to Issuer other than Medicaid/Medicare Account Debtors that their Accounts have been assigned to the Collateral Agent and to collect

such Accounts directly in its own name and to charge collection costs and expenses, including reasonable attorney’s fees, to such Issuer, and (b) Medicaid/Medicare Account Debtors that such Issuer has waived any and all defenses and counterclaims it may have or could interpose in any such action or procedure brought by the Collateral Agent to obtain a court order recognizing the collateral assignment or security interest and lien of the Collateral Agent in and to any Account or other Collateral and that the Collateral Agent is seeking or may seek to obtain a court order recognizing the collateral assignment or security interest and lien of the Collateral Agent in and to all Accounts and other Collateral payable by Medicaid/Medicare Account Debtors.

(v) As and when determined by the Collateral Agent in its sole discretion but not more often than four (4) times per year prior to the occurrence and continuance of an Event of Default, the Collateral Agent may perform the searches described in clauses (a), (b) and (c) below against Issuer, all at Issuer’s expense: (a) UCC searches with the Secretary of State of the jurisdiction of organization of each Issuer and the Secretary of State and local filing offices of each jurisdiction where Issuer maintain their respective executive offices, a place of business or assets; (b) lien searches with the United States Patent and Trademark Office and the United States Copyright Office; and (c) judgment, federal tax lien and corporate and partnership tax lien searches, in each jurisdiction searched under clause (a) above.

(vi) Each Issuer (a) shall provide prompt written notice to its current bank to transfer all items, collections and remittances to the Concentration Account, (b) shall provide prompt written notice to each Account Debtor (other than Medicaid/Medicare Account Debtors) that the Collateral Agent has been granted a lien and security interest in, upon and to all Accounts applicable to such Account Debtor and shall direct each Account Debtor to make payments to the appropriate Lockbox Account, and each Issuer hereby authorizes the Collateral Agent, upon any failure to send such notices and directions within ten (10) calendar days after the date hereof (or ten (10) calendar days after the Person becomes an Account Debtor), to send any and all similar notices and directions to such Account Debtors, and (c) shall do anything further that may be lawfully required by the Collateral Agent to create and perfect the Collateral Agent’s lien on any collateral and effectuate the intentions of the Collateral Documents. At the Collateral Agent’s request, each Issuer shall immediately deliver or make arrangements to deliver to the Collateral Agent all items for which the Collateral Agent must receive possession to obtain a perfected security interest and all notes, certificates, and documents of title, Chattel Paper, warehouse receipts, Instruments, and any other similar instruments constituting Collateral.

(vii) Each Issuer shall give the Collateral Agent at least 30 days’ prior written notice of (i) any change in such Issuer’s name, identity or corporate structure and (ii) any reincorporation, reorganization or other action that results in a change of the jurisdiction of organization of such Issuer.

(viii) If any Event of Default shall have occurred and be continuing, the Collateral Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral), and also may (i) require each Issuer to, and each Issuer hereby agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of the

Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place to be designated by the Collateral Agent that is reasonably convenient to both parties, (ii) enter onto the property where any Collateral is located and take possession thereof with or without judicial process, (iii) prior to the disposition of the Collateral, store, process, repair or recondition the Collateral or otherwise prepare the Collateral for disposition in any manner to the extent the Collateral Agent deems appropriate, (iv) take possession of any Issuer’s premises or place custodians in exclusive control thereof, remain on such premises and use the same and any of such Issuer’s equipment for the purpose of completing any work in process, taking any actions described in the preceding clause (iii), and collecting any Obligation, (v) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable, and (vi) provide entitlement orders with respect to Security Entitlements (as defined in Section 8-102 of the UCC) and other Investment Property constituting a part of the Collateral and, without notice to any Issuer, transfer to or register in the name of the Collateral Agent or any of its nominees any or all of the Securities Collateral (defined below). The Collateral Agent or any Holder may be the purchaser of any or all of the Collateral at any such sale and the Collateral Agent, as agent for and representative of the Holders (but not any Holder in its individual capacity unless Holders of a majority of the principal amount and interest of the Notes shall otherwise agree in writing), shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any Collateral payable by the Collateral Agent at such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Issuer, and each Issuer hereby waives (to the extent permitted by applicable law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Each Issuer agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Issuer of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Issuer hereby waives any claims against the Collateral Agent and the Holders arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent and the Holders accept the first offer received and do not offer such Collateral to more than one offeree; provided that nothing contained herein shall be deemed to be a waiver by any Issuer or any Subsidiary that such sale must be conducted in a commercially reasonable manner and otherwise in accordance with applicable Law. If the proceeds of any sale or other disposition of the Collateral are insufficient to pay all the Obligations, Issuers shall be jointly and severally liable for the deficiency and the fees of any attorneys employed by the Collateral Agent to collect such deficiency. Each Issuer further agrees that a breach of any of the covenants contained in this Section 4(d)(viii) will cause irreparable injury to the Collateral Agent and the Holders, that the Collateral Agent and the Holders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this

Section shall be specifically enforceable against such Issuer, and each Issuer hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Obligations becoming due and payable prior to their stated maturities.

(e) Power of Attorney. The Collateral Agent is hereby irrevocably made, constituted and appointed the true and lawful attorney for Issuer (without requiring the Collateral Agent to act as such, but to be exercised after the occurrence and during the continuance of an Event of Default) with full power of substitution to do the following: (i) endorse the name of any such Person upon any and all checks, drafts, money orders, and other instruments for the payment of money that are payable to such Person and constitute collections on its or their Accounts; (ii) execute in the name of such Person any financing statements, schedules, assignments, instruments, documents, and statements that it is or they are obligated to give the Collateral Agent under any of the Notes Documents; and (iii) do such other and further acts and deeds in the name of such Person that the Collateral Agent may deem necessary or desirable to enforce any Account or other Collateral or to perfect the Collateral Agent’s security interest or Lien in any Collateral (including any additional Collateral pursuant to Sections 6(d) and 6(l)). In addition, if any such Person breaches its obligation hereunder to direct payments of Accounts or the proceeds of any other Collateral to the appropriate Lockbox Account, the Collateral Agent, as the irrevocably made, constituted and appointed true and lawful attorney for such Person pursuant to this paragraph, may, by the signature or other act of any of the Collateral Agent’s officers or authorized signatories (without requiring any of them to do so), direct any federal, state or private payor or fiscal intermediary to pay proceeds of Accounts or any other Collateral to the appropriate Lockbox Account.

(d) Intentionally Deleted.

(e) Redemption Procedures.

(i) Notice to Holders Upon Redemption. In the case of a redemption pursuant to Sections 5(a), 5(b) or 5(c) at least 30 days prior to a redemption date of Notes, except in the case of Section 5(c) for which at least 60 days prior to such redemption date of the Notes, the Company shall mail a notice of redemption by first-class mail to each Holder of Notes at such Holder’s registered address.

The notice shall identify the amount Notes to be redeemed and shall state:

(A) the redemption date;

(B) the applicable subsection of Section 5 pursuant to which the redemption will occur;

(C) if applicable, the Redemption Price and the number of shares into which the Redemption Warrant will be exercisable, on the redemption date;

(D) if applicable, the Premium Redemption Price on the redemption date;

(E) if redemption will occur pursuant to Section 5(c), the Notes or portions of Notes to be redeemed, the Redemption Price and the new Conversion Price that will be in effect for each of the remaining Notes.

(F) that Notes called for redemption must be surrendered to the Company to collect the consideration (or if to an agent of the Company, the name and address of the agent where the Notes must be surrendered); and

(G) that, unless the Company defaults in making such redemption payment interest on the Notes (or portion thereof) called for redemption ceases to accrue on and after the redemption date.

(ii) Such notice shall be accompanied by an Officer’s Certificate and a written opinion from legal counsel from the Company to the effect that such redemption will comply with the conditions herein.

(iii) Once notice of redemption is mailed, Notes called for redemption become due and payable on the redemption date. Upon surrender to the Company, the consideration shall be delivered as stated in the notice. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

(iv) Holders shall be required to surrender the Notes being purchased by the Company, with an appropriate form duly completed, to the Company at the address specified in the notice of redemption. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Securities surrendered.

(v) If any Note surrendered for redemption in the manner provided herein shall not be so paid on the redemption date due to the failure of the Company to deliver the required consideration, interest shall continue to accrue from the redemption date until such consideration is delivered, with such consideration being based on the unpaid principal and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the date and in the manner provided in the Notes which were to be redeemed.

(vi) Any redemption shall be conditioned upon and occur either concurrently with or immediately prior to or after the consummation of the transaction, including without limitation a Change of Control, related to such redemption.

(vii) Holders shall have the right to convert the Notes or any portion thereof in accordance with Section 3 at any time prior to the actual redemption of the Notes or applicable portion of the Notes, including without limitation, during the thirty (30) day (or, in the case of Section 5(c), sixty (60) day) notice period under this Section 5(e).

(f) Tax Put Right.

(i) For 30 days following a redemption in which the Holder receives Redemption Warrants, (A) the Holder shall have a right (the “Tax Put Right”) by written notice to the Company (which such notice shall include the number of shares of Common

Stock desired to be put to the Company and the value thereof as of the date of such notice) to require the Issuers to purchase an amount of shares of Common Stock from the Holder, based on the average Daily Market Price during the ten (10) Trading Days prior to such redemption, that is equal to an amount of up to $5,000,000 in the aggregate for all such redemptions for all Holders of all Notes and (B) if the amount received by the Holder after exercising its rights up to the maximum aggregate amount pursuant to clause (A) is, when combined with the consideration received by the Holder upon redemption of the Convertible Notes, still insufficient to pay the income taxes relating to the redemption, the receipt of the Redemption Warrants and the exercise of the Tax Put Right, then, upon receipt of written notice from the Holder (or any other Holder of Notes) of such insufficiency, the Company shall use commercially reasonable efforts to file one registration statement for all Holders of Notes (regardless of the number of redemptions) as soon as reasonably practicable after such redemption but in any event within thirty (30) days after such redemption and cause such registration statement to be declared effective as soon as practicable after such filing but in any event within sixty (60) days after such filing, failing which the Holders of all Notes shall have an additional Tax Put Right in the amount of up to $2,500,000 in the aggregate for all such redemptions.

(ii) Upon the receipt of notice from a Holder that such Holder has elected to exercise its Tax Put Right, the Company shall promptly, but in no event later than two (2) business days after the receipt thereof, deliver a copy of such notice to the other Holders. For a period of five (5) Business Days following its receipt of a Tax Put Right notice, each other Holder shall have the right and option (but not the obligation) to also exercise a Tax Put Right by delivering written notice thereof (which such notice shall include the number of shares of Common Stock desired to be put to the Company and the value thereof as of the date of such notice). If the Holders electing to exercise their Tax Put Right elect to put more than the aggregate amount of shares that the Company is required to repurchase pursuant to Section 5(f)(i), then each Holder delivering a Tax Put Right notice shall be entitled to require the Company to repurchase that number of shares of Common Stock calculated by multiplying the aggregate number of shares of Common Stock that the Company is required to repurchase pursuant to Section 5(f)(i) by a fraction the numerator of which is equal to the number of shares of Common Stock elected to be repurchased from such Holder and the denominator of which is equal to the total number of shares of Common Stock elected to be repurchased by all Holders that elect to exercise their Tax Put Right.

6. Covenants.

(a) Reservation of Conversion Shares and Common Stock Underlying Waiver Warrants. The Company agrees that it will at all times reserve and keep available out of its authorized shares of Common Stock, free from preemptive rights, solely for the purpose of the issue upon conversion of the Notes, issue upon the exercise of the Waiver Warrants and issuances of shares of Common Stock in accordance with the terms hereof. The Company agrees that the Conversion Shares and shares of Common Stock issued upon the exercise of the Waiver Warrants shall, when issued, be duly and validly issued and fully paid and non-assessable.

(b) Required Registration. The Company agrees that if any Conversion Shares or shares issued upon the exercise of the Waiver Warrants require registration with or approval of any governmental authority under any Federal or state Law, or any national

securities exchange, before such shares may be issued upon conversion, the Company will use its best efforts to cause such shares to be duly registered or approved, as the case may be.

(i) The Issuers covenant and agree that so long as any Notes shall remain outstanding, at any time prior to the Bridge Loan Conversion, the Issuers shall not, and shall not permit any of their Subsidiaries, to directly or indirectly incur, create, assume, guarantee, become or remain liable, contingently or otherwise, with respect to, or otherwise become responsible for the payment of, including, without limitation, by way of assumption or acquisition in a business combination (each event, an “incurrence”) any Indebtedness other than (x) the Notes, (y) Senior Indebtedness in an aggregate principal amount outstanding not to exceed (1) $15 million of which at least $10 million principal amount of such Indebtedness shall be in the form of a revolving loan facility secured by the Issuers’ accounts receivables or other similar asset-based loan plus (2) $3 million principal amount under the Bridge Loan; provided, however that the Issuers may incur additional Senior Indebtedness up to $4 million the proceeds of which shall be used for the sole purpose of paying off the Bridge Loan, and (z) Subordinated Indebtedness.

(ii) The Issuers covenant and agree that so long as any Notes shall remain outstanding, at any time from and after the Bridge Loan Conversion, the Issuers shall not, and shall not permit any of their Subsidiaries, to directly or indirectly incur, create, assume, guarantee, become or remain liable, contingently or otherwise, with respect to, or otherwise become responsible for the payment of, including, without limitation, by way of assumption or acquisition in a business combination (each event, an “incurrence”) any Indebtedness other than (x) the Notes, (y) Senior Indebtedness in an aggregate principal amount outstanding not to exceed $18 million (which amount shall be increased by an amount equal to the cash proceeds (net of any broker, finder’s or transaction fees or commissions incurred in connection therewith, if any) of any cash equity contribution to the Company by Parent, the aggregate amount of which equity contributions shall in no event exceed $7 million), at least $10 million principal amount of which Indebtedness shall be in the form of a revolving loan facility secured by the Issuers’ accounts receivables or other similar asset-based loan; provided however, that the incurrence of any Indebtedness pursuant hereto shall not cause the Consolidated Senior Leverage Ratio to exceed 2.00 to 1.00 for the most recently ended four full Fiscal Quarters for which internal financial statements are available immediately preceding the date on which such Indebtedness is incurred determined on a pro forma basis (including pro a forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred and the application of proceeds therefrom had occurred at the beginning of such four Fiscal Quarter period, and (z) Subordinated Indebtedness. Notwithstanding anything contained in the foregoing to the contrary, the Issuers shall be permitted to incur a minimum of $15 million in Senior Indebtedness, provided that at least $10 million principal amount of such Indebtedness shall be in the form of a revolving loan facility secured by the Issuers’ accounts receivables or other similar asset-based loan.

(iii) Notwithstanding any provision of this Section 6(c) to the contrary, as long as any Obligations (as such term is defined in the Credit Agreement) (or any extensions, modifications, refinancings, renewals and refundings thereof in accordance with the

Intercreditor Agreement) are outstanding under the Credit Agreement and the Credit Agreement has not been terminated, the Issuers shall be permitted, and shall be allowed to permit any of their Subsidiaries, to directly or indirectly incur, create, assume, guarantee, become or remain liable, contingently or otherwise, with respect to, or otherwise become responsible for the payment of, Senior Indebtedness under the Credit Agreement (including any extensions, modifications, refinancings, renewals and refundings thereof in accordance with the Intercreditor Agreement) in the principal amount of $17,000,000 and the provisions of clauses (i) and (ii) above shall not be applicable to any of such Senior Indebtedness unless and until ComVest, Parent or any of their Affiliates becomes the holder of such Indebtedness under the Credit Agreement, whether as a result of the purchase of such Senior Indebtedness pursuant to their exercise of the purchase option under Section 22 of the ComVest Senior Subordination Agreement or otherwise. The limitation on the principal amount of Senior Indebtedness set forth in this clause (iii) shall not limit or otherwise affect the right of the holder of any such Senior Indebtedness to accrue and receive payment of interest (including at the default rate and including postpetition interest), fees, expenses or other charges. Upon the purchase of Senior Indebtedness under the Credit Agreement by ComVest, Parent or any of their Affiliates, this clause (iii) shall be null and void and the limitation on Senior Indebtedness shall be determined pursuant to clauses (i) and (ii) above.

(iv) If on any date the Issuers incur Senior Indebtedness in breach of this Section 6(c) as a result of the aggregate principal amount of Senior Indebtedness exceeding the amount then permitted under subclause 6(c)(i)(y) or 6(c)(ii)(y) hereof, such breach shall not constitute an Event of Default if, and only if, the Issuers shall have concurrently with such incurrence prepaid to the Holder in respect of the outstanding principal amount of the Note an amount equal to 110% of the amount by which the Senior Indebtedness incurred, when aggregated with all such Senior Indebtedness then outstanding, exceeds the maximum aggregate principal amount of Senior Indebtedness then permitted under such subclause 6(c)(i)(y) or 6(c)(ii)(y). In connection with any payment to the Holder under this Section 6(c)(iv), the Issuers shall comply with the procedures applicable to redemption under Section 5(e) (including the giving of a notice to the Holder at least 30 days in advance of any prepayment) to the same extent as if such prepayment was being made as a redemption of the Notes pursuant to the provisions applicable to redemptions under Sections 5 (a) or (b) above.

(d) Limitation on Liens. The Issuers and their Subsidiaries shall not create, incur, assume or suffer to exist any Lien upon, in or against, or pledge of, any of the Collateral or any of their properties or assets or any of their authorized but unissued or treasury shares, securities or other equity or ownership or partnership interests, whether now owned or hereafter acquired, except for Permitted Liens; provided further, if the Issuers and their Subsidiaries shall incur any Liens securing Senior Indebtedness, the Issuers and their Subsidiaries shall cause all Obligations to also be secured by a Lien in favor of the Collateral Agent for the benefit of the Holders, pursuant to a validly created and effective security interest, on a basis junior only to such Senior Indebtedness being so secured, in such manner as is consistent with the Credit Agreement and otherwise reasonably acceptable to the Holders of a majority of the principal amount and interest of the Notes outstanding.

(e) Right to Cure Default of First Priority Lien Indebtedness. The Issuers agree that, upon any default, breach, violation, event, fact or circumstance under any First

Priority Lien Indebtedness (including a Default or Event of Default under the Credit Agreement, as defined therein) which, with the giving of applicable notice or passage of time or both, would permit the holder of such Indebtedness to declare a default or otherwise accelerate amounts due thereunder, which the Issuers have not cured within the permitted time period and RGGPLS or an RGGPLS Permitted Assignee (as defined below) have not elected, within five (5) Business Days of any such event, to repay, refinance or replace such Indebtedness or otherwise cure or provide funding to the Company for the purposes of curing such default (the “RGGPLS Cure”), MHR Fund Management LLC, its Affiliates, and any Person, directly or indirectly, managed or controlled by MHR Fund Management LLC or its Affiliates, including without limitation, MHR Capital Partners Master Account LP, MHR Capital Partners (100) LP and OTQ LLC (collectively “MHR”) shall have the right, but not the obligation, to fund the repayment of such Indebtedness (including, without limitation, by way of purchasing interests in the loans under the Credit Agreement) or otherwise cure such default within five (5) Business Days of the earlier of (i) the expiration of the RGGPLS Cure period above and (ii) the receipt of notice from RGGPLS or any RGGPLS Permitted Assignee that it has elected not to pursue an RGGPLS Cure. The Company shall give MHR written notice of any such default promptly after the occurrence thereof, but in no event later than two (2) Business Days after the occurrence of any such default. For purposes of the foregoing, an “RGGPLS Permitted Assignee” shall mean the surviving entity in a reorganization or recapitalization of RGGPLS, including without limitation, by way of merger or consolidation with or into another person or entity, if the percentage interest of the members or stockholders, as the case may be, in the equity interests of the surviving entity following consummation of such transaction is substantially the same (on a relative basis) as each such stockholder’s percentage interest in RGGPLS immediately prior to the consummation of such transaction. From and after the date of the Bridge Loan Conversion, all references to RGGPLS in this Section 6(e) shall be replaced by Parent, all references to RGGPLS Cure in this Section 6(e) shall be replaced by “ComVest Cure” and references to RGGPLS Permitted Assignee in this Section 6(e) shall be replaced by “Parent Permitted Assignee”.
