                           ($1,000,000). Notwithstanding any provision of this
                           Agreement to the contrary, to the extent trade
                           accounts payable to Purchaser by Seller exceed One

                           obligation for the Trade Payables and, if the
                           transactions contemplated by this Agreement do not

                           and void, and Seller shall again become obligated to
                           Purchaser in the amount of the Trade Payables
                           otherwise forgiven under this section. The
                           forgiveness and payments of trade accounts payable to
                           Purchaser by Seller shall be applied against the

                  C.       Except for those liabilities related to leases and
                           contracts which arise after Closing, and which
                           Purchaser specifically assumes in writing (the

                           Schedule II.C hereto (other than those which
                           Purchaser notifies Seller in writing, on or before
                           July 31, 1998, it will not assume), Purchaser shall

                           foregoing and notwithstanding anything to the
                           contrary set forth herein, in no event shall
                           Purchaser assume or be deemed to assume any of
                           Seller's provider agreements with the federal

                           other governmental payor of health care services
                           (collectively, "Governmental Payors"), and Purchaser
                           shall not be liable in any manner for any liability
                           or obligation of Seller to any Governmental Payor,
                           whether known or unknown, including without
                           limitation any liability for past overpayments, civil
                           monetary penalties or false claims, and any
                           liabilities arising out of any failure of Seller to
                           comply with any law, regulation, rule, manual
                           provision or other requirement applicable to

                           and, except as set forth in Schedule IV.B, the
                           execution, delivery and performance of this

                           and the consummation of the transactions

                  C.       Customers and Customer Relations. Schedule IV.C

                           represents One Hundred Fifty Thousand Dollars
                           ($150,000) or greater of gross billings by Seller's
                           laboratory business over the period from June 1,
                           1997 through June 30, 1998 (each a "Large

                           Schedule IV.C (which will show customer numbers and
                           not names prior to the Closing, unless Seller in its
                           sole discretion determines it is appropriate to
                           disclose a customer to Purchaser before Closing in
                           the interest of joint efforts to preserve the
                           business), to the best of Seller's knowledge, no
                           Large Customer will cease to do business with
                           Purchaser, or materially decrease the volume of
                           revenue under such arrangements after, or as result
                           of the consummation of, the transactions
                           contemplated hereby, or is significantly in arrears
                           in payment of amounts owed to Seller. To the best of
                           Seller's knowledge, Seller has used its reasonable
                           business efforts to maintain good working
                           relationships with all of its customers. Except as
                           set forth in Schedule IV.C, to the best of Seller's
                           knowledge, no Large Customer has given Seller notice
                           terminating, canceling, or   threatening to
                           terminate or cancel any contract or relationship
                           with Seller.

                  D.       Financial Statements. Seller has delivered to
                           Purchaser unaudited statements of income for Seller's
                           laboratory business for the four months ended April
                           30, 1998, and audited statements of income for the
                           year ending December 31, 1997. To the knowledge of
                           Seller, such statement of income fairly presents the
                           total net revenue and provision for doubtful accounts
                           for the Seller's laboratory operations for the period
                           covered by such statement of income, except for
                           disputed claims relating thereto disclosed in writing
                           to Purchaser concurrently with the execution of this
                           Agreement. Said statement of income was prepared in
                           accordance with generally accepted accounting
                           principles, applied on a consistent basis for the
                           periods involved.

                                 business and on Seller's usual terms and
                                 conditions.

                           3.    Increased any liability which would have a
                                 Material Adverse Effect, except in the ordinary

                                 Effect.

                           taken as a whole.

                  F.       No Adverse Change. To the best of the knowledge of
                           Seller, between April 30, 1998, and the date of this
                           Agreement, there has been no adverse change in the
                           financial condition, assets, or business of Seller's
                           laboratory which has resulted in a Material Adverse
                           Effect.

                           be deemed to have knowledge if its Officers engaged
                           in conscious or reckless disregard of facts.

                                 for recoupment by any third party insurer
                                 or government agency or for mandatory or
                                 permissive exclusion under 42 U.S.C. Sec.
                                 1320a-7 or under any other federal or

                                 or state law which would have a Material
                                 Adverse Effect. To the best of Seller's
                                 knowledge, billing by Seller has been
                                 true and correct in all material respects
                                 and in compliance with applicable laws,
                                 regulations and policies except to the
                                 extent such failure would

                                       not have a Material Adverse Effect. To
                                       the best of Seller's knowledge, neither
                                       Seller nor any of its employees or agents
                                       has solicited or obtained specimen
                                       referrals by means of rebates, kickbacks
                                       or other unlawful arrangements or in a
                                       manner otherwise in violation of any
                                       federal, state or local statute or
                                       regulation, which action would have a
                                       Material Adverse Effect.

                  M.       Pending Claims. Except as disclosed in writing to
                           Purchaser's attorney, there is no action, suit,
                           proceeding or claim pending, or, to the knowledge of
                           Seller, threatened against Seller, which relates to
                           the Purchased Assets and there is no outstanding
                           execution, order, writ, injunction, judgment or
                           decree of any court, government or governmental
                           agency against Seller which has a Material Adverse
                           Effect on the Purchased Assets.

                  N.       No Creation of Liens, Etc. Neither the execution of
                           this Agreement nor the consummation of the
                           transactions provided for herein will result in the
                           creation of any lien, charge or encumbrance on any of
                           the Purchased Assets.

                  O.       No Default. To the best of Seller's knowledge, Seller
                           is not in default under any contract, transaction,
                           agreement, lease or instrument to which it is a party
                           or by which it is bound, which would have a Material
                           Adverse Effect.

                  P.       Employees. All employees of Seller performing
                           services for Seller's laboratory operations, all
                           leased employees of Seller performing services for
                           Seller's laboratory operations and all individuals
                           (as opposed to entities) providing services for
                           Seller's laboratory operations as independent
                           contractors are listed on Schedule IV.P attached
                           hereto, which Schedule contains the names, position
                           and salary or other cash compensation paid to such
                           individual. Except as set forth on Schedule IV.P,
                           Seller has no written, or to the best of Seller's
                           knowledge, oral employment agreements or contracts
                           with any of its employees or leased employees and, to
                           the best of Seller's knowledge, no employee or leased
                           employee has an oral or implied employment agreement
                           or contract with the Seller. Seller has no collective
                           bargaining or other agreements with any labor union
                           or similar employee group with regard to its
                           laboratory operations and no union has been certified
                           as a bargaining agent for its employees. Seller has
                           not received any request for representation by any
                           employee or group of employees.

                  Q.       Customer List. As of the Closing Date, Seller will
                           have provided laboratory services to each of its
                           customers indicated on the Customer Lists in the
                           format attached as Schedule I.A.

         VI.      Conditions to Purchaser's Performance. The obligations of
                  Purchaser under this Agreement shall be subject to the
                  satisfaction, on or prior to the Closing Date, of the
                  following conditions:

                  A.       All representations and warranties of Seller
                           contained in this Agreement and in any schedules,
                           certificates or other documents delivered pursuant to
                           this Agreement shall be true, correct and complete in
                           all respects on and as of the date when made and on
                           and as of the Closing Date, and Seller shall have

                           Closing Date, to the foregoing effect.

                  B.       No action or proceeding shall have been instituted or
                           threatened before any court or governmental agency to
                           restrain or prohibit, or to obtain substantial
                           damages in respect of, or which is related to or
                           arises out of, this Agreement or the consummation of
                           the transactions contemplated herein which, in the
                           reasonable opinion of Purchaser, make it inadvisable
                           to consummate such transactions.

                  C.       Purchaser shall have received from Seller's counsel
                           an Opinion substantially in the form attached hereto
                           as Schedule VI.C.

                  D.       Seller shall not have disposed of significant
                           laboratory assets, or incurred significant unusual
                           liabilities or otherwise engaged in significant
                           transactions outside the ordinary course of its
                           laboratory business during such period, which have a
                           Material Adverse Effect, and that there has been no
                           adverse change in the financial condition or business
                           of such laboratory business during such period, which
                           has a Material Adverse Effect. In connection with
                           this condition, Purchaser or its accountants shall
                           have the right to review the accounting and other
                           records of Seller for the period from April 30, 1998
                           to a date selected by Purchaser near the Closing
                           Date.

                  E.       There shall have occurred no damage, destruction or
                           loss, whether or not covered by insurance, adversely
                           affecting in any material respect any of the Tangible
                           Assets to be sold and transferred hereunder.

                  F.       Seller, at the time of closing, except as otherwise
                           may be agreed to in writing by the parties, shall
                           have paid to all such employees all amounts due and

                           pay, bonuses and past service claims, and shall have
                           made and remitted, for all periods through and

                           lessor(s) under the material lease(s) referred to in
                           Paragraph III-C-3 above shall have consented to the
                           assignment of said lease(s) to Purchaser.

                           Agreement, and of the other documents provided for
                           herein, by Seller shall have been approved by the
                           Board of Directors and the shareholders thereof, and
                           by such other persons as are required by applicable
                           law, corporate by-laws or other instruments to
                           provide their approval prior to the consummation
                           thereof, and the Purchaser shall have received a
                           certified copy of such Resolutions or approvals to
                           that effect.

                           any of the covenants and conditions imposed
                           hereunder. Such waiver, however, shall not constitute
                           any waiver of any claim for damages Purchaser may
                           otherwise be entitled to make pursuant to the terms
                           hereof; provided, however, that there shall be no
                           failure of a condition of closing if (a) the
                           aggregate of the amounts in controversy of any
                           Limited Direct Damage Claims (as defined in Section
                           X(D)(1)) which have arisen or been asserted before
                           the Closing is less than $700,000, or (b) the
                           aggregate of the amounts in controversy of any IV(C)
                           Damage Claims (as defined in Section X(D)(5)) which
                           have arisen or been asserted before the Closing is
                           less than $750,000. Any such Limited Direct Damage
                           Claims or IV(C) Damage Claims shall be treated after
                           the Closing Date in accordance with the provisions of
                           Section X.

                  J.       All of the transactions contemplated by the Stock
                           Purchase Agreement dated July 16, 1998 between Seller
                           and Purchaser shall be simultaneously consummated.

                  K.       If determined necessary by the Seller, or required by
                           the Purchaser, any approval of the shareholders of
                           the Seller or the holders of the Seller's 8.25%
                           Convertible Subordinated Debentures due February 1,
                           2006 of the transactions contemplated by this
                           Agreement shall have been obtained.

                  L.       As set forth in Section IX(I), prior to Closing,
                           Purchaser shall be entitled to conduct further due
                           diligence with regard to health care compliance
                           issues. With respect to all laws, regulations and
                           orders applicable to Seller's laboratory business
                           ("Health Care Compliance Issues") as an additional
                           condition to Closing, competent health care counsel
                           shall have determined in his/her reasonable opinion
                           (the entire substance of which opinion shall be
                           disclosed in full to Seller, in writing only if
                           requested by Seller) that no Health Care Compliance
                           Issues, exist with regard to Seller could reasonably
                           be expected to have a Material Adverse Effect (either
                           on the Purchased Assets or Purchaser's operation of
                           the laboratory business after the Closing).

         VII.     Conditions to Performance by Seller. The obligations of Seller
                  under this Agreement shall be subject to the satisfaction, on
                  or prior to the Closing Date, of the following conditions:

                  A.       All representations and warranties of Purchaser
                           contained in this Agreement and in any schedules,
                           certificates or other documents delivered pursuant to
                           this Agreement shall be true, correct and complete in
                           all material respects on and as of the date when made
                           and on and as of the Closing Date, and the Purchaser
                           shall have executed and delivered to Seller
                           certificates, signed by its duly authorized officer,
                           dated as of the Closing Date, to the foregoing
                           effect.

                  B.       The full performance by Purchaser of each and every
                           covenant and condition imposed upon it hereunder,
                           provided, however, that Seller may at its option
                           waive the performance of any of the covenants and
                           conditions imposed hereunder. Such waiver, however,
                           shall not constitute a waiver of any other covenant
                           or condition or constitute any waiver of any claim
                           for damages such party may otherwise be entitled to
                           make pursuant to the terms hereof.

                  C.       No action or proceeding shall have been instituted or
                           threatened before any court or governmental agency to
                           restrain or prohibit, or to obtain substantial
                           damages in respect of, or which is related to or
                           arises out of, this Agreement or the consummation of
                           the transactions contemplated herein which, in the
                           reasonable opinion of Seller, made it inadvisable to
                           consummate such transactions.

                  D.       Seller shall have received from Purchaser's counsel
                           an Opinion substantially in the form attached hereto
                           as Schedule VII.D.

                  E.       The execution, delivery and performance of this
                           Agreement, and of the other documents provided for
                           herein, by Purchaser shall have been approved by the
                           Board of Directors thereof or such other appropriate
                           body, and by such other

                                       12

                           persons as are required by applicable law, corporate
                           bylaws or other instruments to provide their approval
                           prior to the consummation thereof, and the Seller
                           shall have received a certified copy of such
                           Resolutions or approvals to that effect.

                  F.       If determined necessary by the Seller, or required by
                           the Purchaser, any approval of the shareholders of
                           the Seller or the holders of the Seller's 8.25%
                           Convertible Subordinated Debentures due February 1,
                           2006 of the transactions contemplated by this
                           Agreement shall have been obtained.

                  G.       All of the transactions contemplated by the Stock
                           Purchase Agreement dated July 16, 1998 between the
                           Seller and the Purchaser shall be simultaneously
                           consummated.

         VIII.    Covenants with Respect to Competition. Seller warrants that
                  for a period as contained therein, the non-solicitation and
                  non-compete agreements shall be executed and in effect as set
                  forth in Schedule VIII. hereto.

         IX.      Additional Covenants and Agreements.

                  A.       As of the Closing Date, Seller shall be deemed to
                           have assigned to Purchaser all of its right, title
                           and interest in and to such warranties (express and
                           implied) that continue in effect with respect to any
                           of the Purchased Assets, and to have nominated
                           Purchaser as such party's true and lawful attorney to
                           enforce such warranties against such manufacturers,
                           and such party shall execute and deliver such
                           specific assignments of such warranty rights as
                           Purchaser may reasonably request.

                  B.       Purchaser shall have the exclusive right to represent
                           itself as the purchaser of the Purchased Assets of
                           Seller's laboratory business provided, however, that
                           such representations shall not in any manner attempt
                           to convey to the public or to any of Seller's
                           customers or former customers that Purchaser is
                           acting for or on behalf of Seller. All statements and
                           releases concerning this Agreement and the
                           transactions contemplated hereby which are intended
                           or designed to be disseminated to any third party
                           shall be subject to the prior written approval of
                           Purchaser and Seller, provided, however that any
                           party may make any public disclosure required by
                           applicable law or any listing or trading agreement
                           concerning its publicly-traded securities (in which
                           case the disclosing party will use its best efforts
                           to advise the other parties prior to making the
                           disclosure and give the other parties an opportunity
                           to comment).

                  C.       From and after the Closing, Purchaser shall be
                           entitled to all of the books, records, [specimens]
                           and other documents and items of Seller pertaining to

                                       13

<PAGE>   14



                           the Purchased Assets (the "Records") and the
                           customers listed on the Customer List; provided,
                           however, that Seller shall have the right to keep all
                           of the Records necessary for Seller to bill and
                           collect the Seller's accounts receivable until such
                           time as Seller determines that its collection efforts
                           with respect to such accounts receivable are complete
                           (the "Collection Period"). Purchaser agrees that,
                           from and after the Closing, Seller may contact
                           customers listed on the Customer List for the purpose
                           of obtaining information related to billing and
                           collection of accounts receivable and any inquiries
                           by third party payors or government authorities.
                           During the Collection Period, Seller shall afford
                           Purchaser and its agents and representatives with
                           access to the Records retained by Seller. After the
                           Collection Period, Seller shall transfer all of the
                           Records retained to Purchaser and Purchaser shall
                           afford Seller and its agents and representatives with
                           access to all Records thereafter. Purchaser shall
                           maintain all Records for the period of time required
                           by Michigan and United States laws and shall assure
                           complete confidentiality with regard thereto except
                           where disclosure is required by law. The parties
                           agree that no portion of the Purchase Price is
                           allocated to purchase of medical records.

                  D.       It is understood and agreed that Seller and Purchaser
                           will not comply with the provisions of the "Bulk
                           Sales Law" or similar provisions of the laws of any
                           state insofar as they may be applicable to the
                           transactions contemplated by this Agreement. Seller
                           agrees to pay and discharge, promptly and diligently,
                           when due, or to contest or litigate all claims of
                           creditors which could be asserted against Purchaser
                           or the Purchased Assets by reason of such
                           noncompliance, to indemnify, defend at its own
                           expense and hold Purchaser harmless from and against
                           any and all such claims and, upon receipt of written
                           notice from Purchaser of the existence thereof, to
                           take promptly all necessary action to remove or cause
                           to be removed any lien or encumbrance which may be
                           placed on any of the Purchased Assets by a creditor
                           of Seller by reason of such noncompliance.

                  E.       The parties agree that Seller's accounts receivable
                           shall not be included among the Purchased Assets. The
                           parties agree that if either party receives payment
                           for services provided by the other party, such party
                           shall promptly (no later than two weeks) turn such
                           payment over to the party to whom the payment is
                           owed.

                  F.       Purchaser assumes responsibility for taking all
                           necessary action, at its own expense to obtain,
                           transfer or continue any licenses, permits or other
                           governmental approvals necessary to the operation of
                           its business at Seller's former laboratory facility.
                           Seller agrees to cooperate fully in the obtaining
                           transfer or continuance of such licenses, permits or
                           approvals.

                  G.       With regard to work in process at Closing, each party
                           agrees that Purchaser shall be responsible for
                           completing performance for all tests received prior
                           to the Closing Date.

                  H.       Seller shall use its best efforts as requested by
                           Purchaser to address any customer concerns relating
                           to this transaction. Seller shall, among other
                           efforts, meet with customers and Purchaser when so
                           requested by Purchaser. Prior to the Closing Date,
                           Seller agrees not to dispose of significant
                           laboratory assets, or incur significant unusual
                           liabilities, or otherwise engage in significant
                           transactions relating to its laboratory business
                           outside of the ordinary course of its laboratory
                           business.

                  I.       Prior to the Closing Date, Purchaser shall be
                           entitled, upon reasonable request, through its
                           employees and representatives, including, without
                           limitation, its attorneys, to perform an
                           investigation (including but not limited to Health
                           Care Compliance Issues) of the assets, properties,
                           business, and operations of Seller, including a
                           review of Seller's books, records, and financial
                           condition including, but not limited to actual and
                           existing minute books and stock records of Seller
                           which are in the current possession and control of
                           the present officers of Seller. Any such
                           investigation and review shall be conducted at
                           reasonable times and under reasonable circumstances.
                           Purchaser agrees that any such investigation or
                           review shall not unreasonably interfere with the
                           ongoing operations of Seller. Seller will cooperate
                           and shall cause its officers, employees, consultants,
                           agents, accountants, and attorneys to cooperate with
                           such employees and representatives in connection with
                           such review and investigation. If this Agreement
                           terminates, Purchaser shall keep confidential and
                           shall not use in any manner any information or
                           documents obtained from Seller concerning its assets,
                           properties, business, and operations. If this
                           Agreement terminates, any documents and copies
                           thereof obtained by Purchaser from Seller shall be
                           promptly returned to Seller.

         X.       Indemnification.

                  A.       Indemnification by Purchaser. Purchaser hereby agrees
                           to indemnify, defend and hold harmless Seller, its
                           officers, directors, employees, shareholders, agents
                           and its successors and assigns, against any and all
                           liabilities, obligations, losses, damages, demands,
                           claims, assessments, actions, tax deficiencies,
                           penalties and interest, reasonable accounting and
                           attorneys' fees, costs and expenses (individually a
                           "Loss" and collectively "Losses"), arising out of, or
                           incident to, any of the following:

                           1.    Any misrepresentation, or breach of any
                                 warranty of Purchaser contained in this
                                 Agreement;

                           2.    Any breach of any covenant, agreement or other
                                 term or provision hereof to be performed by
                                 Purchaser;

                           3.    The Purchaser's operations after the Closing
                                 Date, including, but not limited to, all
                                 claims arising on or after the Closing Date
                                 with respect to the Assumed Liabilities;

                           4.    All claims asserted against the Seller or
                                 its assets and alleged to arise out of any
                                 act, omission, obligation or liability of
                                 Purchaser or any of its officers, employees
                                 or other agents.

                  B.       Indemnification by Seller. Seller hereby agrees to
                           indemnify, defend and hold harmless Purchaser, its
                           officers, directors, employees, shareholders, agents
                           and its successors and assigns, against any and all
                           liabilities, obligations, losses, damages, demands,
                           claims, assessments, actions, tax deficiencies,
                           penalties and interest, reasonable accounting and
                           attorneys' fees, costs and expenses (individually a
                           "Loss" and collectively "Losses"), arising out of, or
                           incident to, any of the following:

                           1.    Any misrepresentation, or breach of any
                                 warranty of Seller contained in this Agreement;

                           2.    Any breach of any covenant, agreement or other
                                 term or provision hereof to be performed by
                                 Seller;

                           3.    With the exception of the Assumed Liabilities,
                                 all liabilities of Seller, whether accrued,
                                 absolute, contingent or otherwise, and whether
                                 due or to become due, including but not limited
                                 to claims with respect to the Retained
                                 Liabilities; and

                           4.    All claims asserted against the Purchaser or
                                 the Purchased Assets and alleged to arise out
                                 of any act, omission, obligation or liability
                                 of Seller or any of its officers, employees or
                                 other agents.

                  C.       Claims. If either party desires to make a claim
                           against the other under Section X(A) or X(B) hereof
                           which does not involve a claim by any person other
                           than the parties, then such party shall make such
                           claim by promptly delivering notice to the other in
                           the form set forth in (1) below. If either party (the
                           "Claimant") desires to make a claim for indemnity
                           against the other (the "Indemnitor") under this
                           Agreement which involves a demand, claim or


                                       16
<PAGE>   17



                           threat of litigation or the actual institution of any
                           action, suit or proceeding (collectively, a "Claim")
                           by a person other than the parties, then such Claim
                           will be made in the following manner and be subject
                           to the following terms and conditions unless
                           otherwise provided for in this Agreement:

                           1.    Notice. The Claimant will give prompt notice
                                 (and, if served with a complaint, not later
                                 than seven (7) days after such service) to the
                                 Indemnitor of any Claim at any time served on
                                 or instituted against the Claimant with respect
                                 to which the Claimant believes it would have a
                                 right of indemnification under this Agreement,
                                 setting forth in reasonable detail the facts
                                 relating to such claim and the basis for its
                                 alleged right of indemnification under this
                                 Agreement; provided, that failure to give
                                 notice as provided above shall not relieve
                                 Indemnitor of its obligations under this
                                 Section X except to the extent Indemnitor is
                                 actually prejudiced thereby.

                           2.    Responsibility for Defense. Within thirty (30)
                                 days after receipt of such Notice, but not less
                                 than five (5) business days prior to the time
                                 the Claimant is required to respond to a Claim
                                 (subject to the proviso contained in Section
                                 X(C)(1)), the Indemnitor will, by giving
                                 written notice to the Claimant, have the right
                                 to assume responsibility for the defense of the
                                 Claim in the name of the Claimant or otherwise
                                 as the Indemnitor may elect; provided, however,
                                 that the Indemnitor's determination to conduct
                                 a defense of a Claim shall in no way be deemed
                                 a conclusive admission of an obligation to
                                 indemnify hereunder. Otherwise, the Claimant
                                 will have responsibility for the defense of the
                                 Claim. Subject to the provisions of subsections
                                 (3) and (4) below, the party having
                                 responsibility for the defense of the Claim
                                 (the "Defending Party") will have the full
                                 authority to defend, cure, adjust, compromise
                                 or settle such Claim or appeal any judgment or
                                 ruling of court or other tribunal in connection
                                 with such Claim in its own name and/or in the
                                 name of the other party.

                           3.    Right to Participate. Notwithstanding a
                                 Defending Party's responsibility for the
                                 defense of a Claim, the other party shall have
                                 the right to participate, at its own expense
                                 and with its own counsel, in the defense of a
                                 Claim and the Defending Party will consult with
                                 the other party from time to time on matters
                                 relating to the defense of such Claim. The
                                 Defending Party shall provide the other party
                                 with copies of all pleadings and material
                                 relating to such Claim.

                           4.    Settlement. A Defending Party will provide the
                                 other party with timely written notice of any
                                 proposed adjustment, compromise or


                                       17
<PAGE>   18



                                 other settlement, including equitable or
                                 injunctive relief, of a Claim which the
                                 Defending Party intends to propose or accept.
                                 If the other party fails to provide the
                                 Defending Party with timely written notice of
                                 objection to such settlement, then the
                                 Defending Party shall have the authority to
                                 propose or accept such settlement and enter
                                 into any agreement, in its own name and/or in
                                 the name of the other party, giving legal
                                 effect to all aspects of such settlement. If
                                 the other party objects to such settlement,
                                 then the Defending Party may, if it so elects,
                                 tender the defense to the other party by paying
                                 to such other party the amount of money
                                 proposed to be paid in settlement of the claim,
                                 in which case the Defending Party shall have no
                                 further liability to the other party hereunder
                                 with respect to such Claim and the other party
                                 shall have full authority for the future
                                 defense of such Claim and full responsibility
                                 for any and all liabilities, obligations, costs
                                 and expenses resulting therefrom.
                                 Notwithstanding anything above to the contrary,
                                 Seller shall not enter into any settlement
                                 which will in any way, financially or
                                 otherwise, affect Purchaser's operation of the
                                 laboratory business.

                  D.       Limitations on Indemnification. The right of either
                           party to indemnification under this Section X of the
                           Agreement shall be subject to the following
                           provisions:

                           1.    The limitations contained in sections 2, 3, and
                                 4 below shall only apply to indemnification for
                                 damage claims by one party against the other
                                 party relating to damages directly incurred by
                                 the Claimant for breach of the representations
                                 and warranties in Sections IV(D) through IV(S)
                                 inclusive and in Section V(C) hereof ("Limited
                                 Direct Damage Claim"). Notwithstanding anything
                                 contained herein to the contrary, there shall
                                 be no limitation of any kind on indemnification
                                 rights in any way relating to third-party
                                 claims, including but not limited to claims by
                                 patients, governmental entities, employees and
                                 customers, asserted against the Claimant for
                                 which the other party is required to indemnify
                                 Claimant ("Third Party Claims"). The
                                 limitations shall be narrowly construed to
                                 ensure that the parties will be fully
                                 indemnified for Third Party Claims.

                           2.    No Limited Direct Damage Claim shall be
                                 payable to the Claimant unless the total
                                 losses for which Limited Direct Damage
                                 Claims are or have been $200,000 in the
                                 aggregate, whereupon the Claimant would be
                                 entitled to the excess losses over $200,000
                                 in the aggregate.

                           3.    Once the total losses for Limited Direct
                                 Damage Claims exceed $200,000 in the
                                 aggregate, losses for each party relating to
                                 Limited Direct Damage Claims shall not
                                 exceed an aggregate of an additional
                                 $500,000.
                                 
                           4.    Limited Direct Damage Claims shall survive
                                 the Closing Date for a period of one (1)
                                 year. Any Limited Direct Damage Claim must
                                 be asserted within the foregoing period.

                           5.    The limitations contained in this section 5 and
                                 section 6 below shall only apply to

                                 against Seller relating to damages directly
                                 incurred by Purchaser for breach of the
                                 representations and warranties in Section IV(C)
                                 hereof ("IV(C) Damage Claim"). No IV(C) Damage
                                 Claim shall be payable to Purchaser unless the
                                 total losses for IV(C) Damage Claims are or
                                 have been $750,000 in the aggregate, whereupon
                                 the Purchaser would be entitled to the excess
                                 losses over $750,000 in the aggregate.

                           6.    Any damages recoverable by Purchaser on a IV(C)
                                 Damage Claim shall be offset by any profits
                                 (calculated consistently with any determination
                                 of damages) derived by Purchaser from the
                                 business prospects listed on Schedule X.D.6
                                 (which will show customer numbers and not names
                                 prior to the Closing) to be supplied by Seller
                                 to Purchaser.

                           7.    IV(C) Damage Claims shall survive the Closing
                                 Date for a period of one (1) year. Any IV(C)
                                 Damage Claim must be asserted within the
                                 foregoing period.

                           8.    The limitations contained in Paragraphs 2, 3
                                 and 4 with respect to Limited Direct Damage
                                 Claims shall be determined and shall operate
                                 independently of the limitations set forth in
                                 Paragraphs 5, 6 and 7 with respect to IV(C)
                                 Damage Claims.

                  E.       Mitigation of Losses. A Claimant shall be entitled to
                           recover the full amount of any Losses incurred due to
                           the matter for which indemnification is sought,
                           including reasonable attorney's fees incurred in
                           connection therewith, but any recovery shall be net
                           of any economic benefit to which the Claimant is
                           entitled due to such Losses, including, without
                           limitation, (a) any insurance proceeds, (b) any
                           payments received from third parties relating to the
                           matter, and (c) any refunds from third party payors
                           attributable to services rendered by Seller prior to
                           the Closing.

                  F.       Remedies. The rights and remedies of each party
                           hereto arising by reason of an inaccuracy in, or
                           breach of the representations and warranties in
                           Sections IV(D) through IV(S) inclusive, and Section
                           V( C) as set forth in D, above, shall be limited to
                           the indemnification right set forth in this Section.

         XI.      Seller's Laboratory Employees. Purchaser agrees to reimburse
                  Seller up to fifty percent (50%) of Seller's liability, if
                  any, pursuant to the WARN Act. Purchaser's liability to Seller
                  pursuant to the WARN Act shall be capped at $250,000. Seller
                  agrees that it shall bear sole responsibility for all costs
                  and expenses, including but not limited to severance pay and
                  related obligations, with regard to its employees. Purchaser
                  shall in good faith offer employment to such of Seller's
                  employees as Purchaser deems necessary for its laboratory
                  operations. Seller shall cooperate with and shall not impair
                  Purchaser's efforts to obtain the employment of such persons.
                  Purchaser shall attempt to provide Seller prior to Closing
                  with a list of such persons to whom it intends to offer
                  employment. The parties agree that, in the event Purchaser
                  requests Seller to temporarily continue the employment of any
                  of its employees following the Closing to aid in the business
                  transition, Seller shall attempt to continue to employ such
                  persons (but does not guarantee the willingness or
                  availability) for the period requested by Purchaser following
                  the Closing, and Purchaser shall promptly reimburse Seller for
                  the direct employee costs incurred by its connection
                  therewith.

         XII.     Termination.

                           3.    By either the Purchaser or Seller, if a

                                 Purchaser, that in order to consummate the

                                 fulfilled for reasons beyond the reasonable
                                 control of Purchaser and are not waived by
                                 Purchaser.
                                 
                           6.    By the Seller, if any of the conditions set

                           7.    By the Seller under the following
                                 circumstances: In the event the Board of
                                 Directors of the Seller receives a proposal
                                 that, in the exercise of its fiduciary
                                 obligations (as determined in good faith by the
                                 Board of Directors), it determines to be a
                                 Superior Proposal (as defined below), the Board
                                 of Directors may, after complying with Section
                                 XIII, withdraw or modify its approval or

                                 Proposal, and/or terminate this Agreement. For
                                 purposes of this Agreement, a "Superior
                                 Proposal" means any bona fide proposal for the
                                 purchase of the Customer List and other assets
                                 of Seller, for a merger or other business
                                 combination involving the Seller or its
                                 Subsidiaries, or for the purchase of an equity
                                 interest in Seller contingent on Seller not
                                 selling the Customer List, in each case, on
                                 terms which the Board of Directors of Seller
                                 determines in its good faith reasonable
                                 judgment to be more favorable to Seller's
                                 shareholders than the transactions contemplated
                                 hereby.

                  B.       Except as set forth in Section XIV, if this Agreement
                           is terminated pursuant to this Article XII, this
                           Agreement shall become void and of no effect with no
                           liability on the part of any party hereto; provided,
                           however, that if the election to terminate is due to
                           the default of a party hereunder, then the
                           non-defaulting party shall be entitled to any and all
                           remedies available at law or in equity.

                                         the same meaning as "Superior
                                         Proposal," except an Acquisition
                                         Proposal shall not yet have been
                                         evaluated by Seller's Board of
                                         Directors and shall not include any
                                         proposal by the Purchaser.


                  B.       Neither the Board of Directors of Seller nor any

                           manner adverse to Purchaser, the approval or
                           recommendation by such Board of Directors or any such
                           committee of this Agreement (or the other

                           Proposal. Notwithstanding the foregoing, in the event

                           in the exercise of its fiduciary obligations (as
                           determined in good faith by the Board of Directors),
                           it determines to be a Superior Proposal (as defined
                           above), the Board of Directors may (subject to the
                           following sentences) withdraw or modify its approval
                           or recommendation of this Agreement or the other
                           transactions contemplated hereby, approve or
                           recommend any such Superior Proposal, enter into an
                           agreement with respect to such Superior Proposal or
                           terminate this Agreement, in each case at any time
                           after the second business day following Purchaser's
                           receipt of a written notice (a "Notice of Superior
                           Proposal") advising Purchaser that the Board of
                           Directors has received a Superior Proposal,
                           specifying the material terms and conditions of such
                           Superior Proposal and identifying the person making
                           such Superior Proposal.

                  C.       In addition to the obligations of Seller set forth in
                           Section XIII above, Seller shall promptly advise
                           Purchaser orally and in writing of any request for
                           information or of any Acquisition Proposal, or any
                           inquiry with respect to or which could lead to any
                           Acquisition Proposal, the material terms and
                           conditions of such request, Acquisition Proposal or
                           inquiry, and the identity of the person making any
                           such Acquisition Proposal or inquiry. Seller will
                           keep Purchaser fully informed of the status and
                           details of any such request, Acquisition Proposal or
                           inquiry.

                  D.       Seller shall immediately cease and cause to be
                           terminated all existing discussions and negotiations,
                           if any, with any parties (other than Purchaser)
                           conducted heretofore with respect to any Acquisition
                           Proposal.

         XIV.     Termination Fee. So long as Purchaser has not materially
                  breached its obligations under this Agreement, Seller shall
                  pay Purchaser, immediately available funds in the amount of
                  Four Hundred Fifty Thousand Dollars ($450,000) upon
                  termination of this Agreement pursuant to Section XII(A)(7).
                  The parties agree that the termination fee is intended, among
                  other things, to cover Purchaser's opportunity costs, loss of
                  benefit of the bargain, and actual expenses incurred, and
                  Seller agrees that such fee is fair and reasonable under the
                  circumstances.

         XV.      General Provisions.

         3.    Representations and Warranties of the Purchaser. The Purchaser
represents and warrants to the Company as follows:

         3.1   Investment Representations. The Purchaser is purchasing the
Purchased Shares for its own account for investment and not with a view to or
for sale or transfer, except for sales or transfers permitted hereunder.

         3.2   Status of Investor.

               (a)     The Purchaser is an Accredited Investor as that term is
defined in Regulation D (17 C.F.R. 230.501 - 230.506).

               (b)     The Purchaser was not organized for the specific purpose
of acquiring the Purchased Shares.

               (c)     The address set forth on the first page of this letter is
the Purchaser's principal place of business, unless otherwise disclosed to the
Company in writing.

         3.3   Restrictions. The Purchaser is aware that the Purchased Shares
delivered hereunder have not been registered under the Securities Act, or under
applicable state securities laws, and that the Company in issuing the Purchased
Shares will be relying upon, among other things, the Purchaser's representations
and warranties contained in Section 3 of this Agreement, in concluding that such
issuance is a "private offering" and does not require compliance with the
registration provisions of the Securities Act and applicable state securities
laws. The Purchaser will not sell, transfer or otherwise dispose of the
Purchased Shares except in compliance with Section 3.7 of this Agreement. In
addition, the Purchaser is aware that the Purchased Shares shall contain the
following legend:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933 OR UNDER ANY OTHER SECURITIES LAWS.
         THEY MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT AS TO THESE SECURITIES UNDER SAID ACT AND ANY
         OTHER APPLICABLE 

                                       8
<PAGE>   9


          SECURITIES LAW, OR AN OPINION OF COUNSEL REASONABLY
          SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION
          IS NOT REQUIRED OR A WRITTEN ADVICE FROM THE SECURITIES
          AND EXCHANGE COMMISSION AND APPLICABLE STATE SECURITIES
          AGENCIES, OR A MEMBER OF THE STAFF THEREOF,  THAT
          "NO-ACTION" WOULD BE RECOMMENDED IF THE PROPOSED
          TRANSFER WERE TO BE MADE WITHOUT THE FILING OF A        
          REGISTRATION STATEMENT (OR ANY COMBINATION OF   THE     
          FOREGOING).

The Purchaser agrees that the Company may issue instructions to its transfer
agent to place, or may itself place, a "stop transfer order" with respect to the
Purchased Shares, provided, however, that such "stop transfer orders" shall not
be enforced if the Purchased Shares are sold or transferred in a transaction
which complies with Section 4.7 hereof.

         3.4    Access. The Purchaser has received and reviewed a copy of the
following documents: (a) the Company's Annual Report on Form 10-K, and the
amendment thereto on Form 10-K-A, for the fiscal year ended December 31, 1997,
and (b) the Company's Quarterly Report on Form 10-Q for the period ended March
31, 1998 (the "SEC Filings"). The Purchaser has been given access to the
Company's facilities, records and books; the Purchaser has had an opportunity to
ask questions of and receive answers from the Company and its officers and
directors concerning the Company, its subsidiaries and the terms and conditions
of the sale of the Purchased Shares and to obtain any additional information
which the Company possesses or can acquire without unreasonable effort or
expense that is necessary to verify the accuracy of the information furnished to
the Purchaser; and the Purchaser has made such investigation and examination of
the affairs of the Company and its subsidiaries and have obtained such
information relating thereto as the Purchaser deems necessary. The Purchaser
understands that the Purchased Shares issuable pursuant to this Agreement are
"restricted securities" within the meaning of Rule 144 (17 C.F.R. 230.144)
promulgated under the Securities Act, and that they must be held indefinitely,
unless they are subsequently registered under the Securities Act, and under
applicable securities laws, or exemptions from such registrations are available.

         By virtue of the Purchaser's investment acumen, knowledge and business
experience and independent advice, the Purchaser is capable of understanding and
evaluating the risks, hazards and merits of participating in the purchase of
Purchased Shares to be made by the Purchaser. The Purchaser has substantial
financial means and is able to bear the economic risk of participating in the
purchase of the Purchased Shares.

         3.5    Due Execution of Agreement. This Agreement, the Voting
Agreement, the Shareholders' Agreement, the Co-Marketing Agreement, the NBD
Subordination Agreement and the Security Agreement have been duly authorized,
executed and delivered by the Purchaser and constitute the legal, valid and
binding obligations of the Purchaser enforceable in accordance with their
respective terms, except as may be limited by bankruptcy, insolvency,
reorganization,

generally and by general principles of equity whether considered in a proceeding
at law or in equity.

warranty, representation and covenant contained in Section 3 of this Agreement
is a material inducement to the Company to enter into and to perform each of the
obligations undertaken by it in this Agreement and to sell the Purchased Shares.

         3.7    Transferability. The Purchaser hereby agrees that it will not
transfer any of its Purchased Shares without an effective registration statement
relating thereto, or an opinion of counsel reasonably satisfactory to the
Company that such registration is not required under the Securities Act and
applicable state law, or a written advice from the SEC and applicable state
securities agencies, or a member of the staff thereof, that "no-action" would be
recommended if the proposed transfer were to be made without the filing of a
registration statement (or any combination of the foregoing). In addition, the
Purchaser hereby agrees that it will not transfer any of its Purchased Shares
except in compliance with the Shareholders Agreement.

         3.8    Incorporation. The Purchaser has been duly incorporated and is
validly existing as a corporation in good standing under the laws of the State
of Delaware with corporate power and authority to own, lease and operate its
properties and to conduct its business as now conducted and to enter into and
perform its obligations under this Agreement.

         3.9    Due Authorization. The execution, delivery and performance of
this Agreement, the Voting Agreement, the Shareholders' Agreement, the
Co-Marketing Agreement, the NBD Subordination Agreement and the Security
Agreement and the consummation of the transactions contemplated herein and
compliance by the Purchaser with its obligations hereunder have been duly
authorized by all necessary corporate action and will not conflict with or
constitute a breach of, or default under, or result in the creation or  
imposition of any lien, charge or encumbrance upon any property or assets of
the Purchaser or any of its subsidiaries pursuant to, any contract, indenture,
mortgage, loan agreement, note, lease or other instrument to which the
Purchaser or any of its subsidiaries is a party or by which it or any of them
may be bound, or to which any of the property or assets of the Purchaser or any
of its subsidiaries is subject, nor will such action result in any violation of
the provisions of the charter or by-laws of the Purchaser or any applicable
law, administrative regulation or administrative or court decree.

         3.10   Consents. No authorization, approval or consent of any court or
governmental authority or agency is necessary in connection with the execution,
delivery and performance of this Agreement, the Voting Agreement, the
Shareholders' Agreement, the Co-Marketing Agreement, the NBD Subordination
Agreement and the Security Agreement by the Purchaser and the consummation of

obligations thereunder.

set forth in this Agreement, each of the parties agrees to use reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, and to assist and cooperate with the other parties in doing, all things
reasonably necessary, proper or advisable to consummate and make effective, in  
the most expeditious manner practicable, the transactions contemplated by this
Agreement; provided that the foregoing shall not prohibit the Board of
Directors of the Company from taking any action permitted by Section XIIA.7. of
the Purchase Agreement and shall not require the Purchaser or


                                       13
<PAGE>   14


the Company to enter into any of the Other Agreements which are not exhibits

Purchaser and the Company

                  (b)      By either the Purchaser or the Company, if the

                  (c)      By Purchaser if any of the conditions set forth in
Section 5(a) shall not be fulfilled for reasons beyond the reasonable control of
Purchaser and are not waived by Purchaser.

the Company and are not waived by the Company.

         If this Agreement is terminated pursuant to this Section 7, this
Agreement shall become void and of no effect with no liability on the part of
any party hereto; provided, however, that, if the election to terminate is due
to the default of a party hereunder, then the non-defaulting party shall be
entitled to any and all remedies available at law or in equity.

         8.       Covenants.

                  (a)      Company Covenants. Until the payment of the
Co-Marketing Termination Fee provided for under the Co-Marketing Agreement (the

                           (i)      Information and Financial Reports.  The
                                    Company shall:

                                    (A)     deliver to Purchaser as soon as
         possible, and in any event within 90 days after the close of each

         the Company and its consolidated subsidiaries as of the close of each
         such fiscal year and audited consolidated statements of income, cash
         flows and stockholders' equity of the  Company and its consolidated
         subsidiaries for the fiscal year then ended, accompanied by an audit

         public accountant firm of national recognition.

                                    (B)     deliver to Purchaser as soon as
         available, and in any event within 45 days after the close of each

         of the Company and its subsidiaries as of the close of each such


                                       14
<PAGE>   15


         fiscal quarter and unaudited consolidated statements of income, cash
         flows and stockholders' equity of the Company and its subsidiaries for
         the fiscal quarter and from the beginning of the fiscal year to the

                                    (C) deliver to Purchaser within 45 days
         after the end of each calendar month of each fiscal year of the
         Company, unaudited financial statements of the Company, including an
         unaudited consolidated balance sheet of the Company and its

         statements of income and cash flows of the Company and its
         subsidiaries for such month and for the period from the beginning of
         the fiscal year to the end of that month.

                           (ii)     Directors and Officers' Insurance.  Subject
to the approval of the Board of Directors as to the reasonableness of applicable
premiums, the Company shall use reasonable efforts to maintain directors and
officers' insurance ("D&O Insurance") with an aggregate loss limit of at least
$7,000,000, the amount in effect as of the date of this Agreement. The Company's
current D&O Insurance policy is attached as Exhibit 8(a)(ii).

                           (iii)    Restrictions on Dividends, Redemptions and
Repurchases. The Company will give the Purchaser written notice (a "Distribution
Notice") at least thirty (30) days prior to the approval by the Board of
Directors of any of the following actions (or if Board approval is not required
or will not be obtained, at least thirty (30) days prior to the occurrence of
any of the following actions):


                                    (A)     payment or declaration of any
         dividend on any shares of capital stock of the Company, common or
         preferred, (except dividends with respect to shares of common stock
         payable solely in shares of common stock), or

                                    (B)     making of any other distribution on
         account of any shares of capital stock of the Company, common or
         preferred, or 

                                    (C)     redemption, purchase or other
         acquisition, directly or indirectly, any shares of capital stock of
         the Company, common or preferred.

(collectively, "Distributions"). For the thirty (30) days following such notice
(the "Distribution Notice Period"), the Purchaser may elect (the "Purchaser's
Election") to terminate the Co- Marketing Agreement pursuant to Section 9(b)
thereof as though the Co-Marketing Agreement was being terminated by Purchaser
without cause, in which case, the Co-Marketing Termination Fee shall become due
and payable in full by the Company on the effective date of the termination of
the Co-Marketing Agreement. Following the Company's receipt of the Purchaser's
Election, no Distribution may be approved or made (unless being made pursuant to
a prior Distribution Notice, the Distribution Notice Period for which terminated
without the Purchaser making a Purchaser's Election) before the payment by the
Company of the Co-Marketing Termination Fee





                                      15
<PAGE>   16


in full, other than as required by the terms of NBD Warrant. In addition to the
prohibition set forth above, the Company will not make any Distribution unless,
after giving effect thereto, the aggregate amount of all such Distributions
(including Distributions under the NBD Warrant) made after December 31, 1998
would not exceed the sum of (1) 50% of Consolidated Net Income for the period
commencing on January 1, 1998 to and including the date of the making of the
proposed Distribution, computed on a cumulative basis for such entire period,
(2) plus the net cash proceeds received by the Company from the sale, subsequent
to the Closing Date, of shares of its capital stock, plus (3) the aggregate
principal amount of Debentures converted, after the Closing Date, into shares of
Common Stock of the Company or (ii) except as required by the NBD Warrant.

"Consolidated Net Income" shall mean for any period the Net Income of the
Company and its subsidiaries for such period determined on a consolidated basis
in accordance with GAAP consistently applied and after eliminating earnings or
losses attributable to outstanding minority interests in the capital stock of
any subsidiary.

"GAAP" shall mean generally accepted accounting principles in effect from time
to time.

"Net Income" of any person means, for any period, the net income (or the net
deficit) of such person for such period, determined in the following manner:

                           (A) The gross revenues and other proper income
         credits of such person shall be computed for such period in accordance
         with GAAP; provided, however, that in any event there shall not be
         included in such gross revenues and income credits any of the following
         items: (i) any proceeds of any life insurance policy; (ii) any
         restoration to income of any contingency or other reserve resulting
         from unusual or non-recurring transactions, (iii) any net gain arising
         from any sale or other disposition of any capital assets, and (iv) any
         gain arising from or represented by items which would, in accordance
         with GAAP, require separate treatment or classification in the
         preparation of financial statements.

                           (B) From the amount of such gross revenues and other
         proper income credits for such period, determined as provided in the
         preceding clause (a), there shall be deducted an amount equal to the
         aggregate of all expenses and other proper income charges, exclusive of
         (i) any losses arising from any write-down or abandonment of any
         capital assets and of any losses arising from the sale or other
         disposition of any capital assets, and (ii) any charge or expense which
         would, in accordance with GAAP, require separate treatment or
         classification in the preparation of financial statements for such
         period, determined in accordance with GAAP.

                           (iv) Amendments.  The Company shall not amend,
modify or repeal any provision of the Articles of Incorporation (except for the
Amendment, solely in terms of the number of shares of capital stock of the
Company authorized) or the By-laws of the Company which changes the rights of
the holders of Common Stock as set forth in the Articles of Incorporation and
the By-laws of the Company as of the date of the Agreement or which would


                                       16
<PAGE>   17


prohibit the Company from paying the Co-Marketing Termination Fee or adversely
affects the rights of the Purchaser under the Agreement, the Voting Agreement,
the Co-Marketing Agreement or the Security Agreement.

                           (v)     Limitation on Debt. Prior to August 31, 2000,
the Company will not, and will not permit its subsidiaries to, become liable for

                                   (A)     Up to $4,000,000 in Senior Debt (as

         Senior Debt at June 30, 1999 and $6,000,000 in Senior Debt at June 30,
         2000.

                                   (B)     Capital Leases in effect at the
         Closing Date and up to $1,000,000 in Capital Leases and Purchase Money
         Debt in each calendar year thereafter.

                                   (C)     Up to $1,500,000 in Letters of
         Credit (as defined below).

                                   (D)     Debt due to the Purchaser.

"Debt" means all liabilities of the Company and its subsidiaries for or in

obligations to such customers under managed care agreements between the customer
and the Company. "Capital Leases" are leases of property, the obligations for
rental of which are required to be capitalized on the consolidated balance sheet
of the Company in accordance with GAAP. "Purchase Money Debt" is Debt incurred
by the Company or its subsidiaries to acquire property which is secured solely
by such property or other property securing Purchase Money Debt.

                           (vi)     Restrictions on Piggyback Registration
 Rights.  The Company will not grant to any other person rights to have their
shares of Common Stock participate in a Piggyback Registration (as defined
below) in a manner superior to the Purchased Shares held by the Purchaser
(except for an Initiating Shareholder (as defined below)), but rather shall
cause the Purchased Shares and such shares of Common Stock to be included in any
such Piggyback Registration in proportion to the number of shares the Purchaser
and each such person request be


                                       17
<PAGE>   18



included in such Piggyback Registration. The Company shall deliver notice to the
Purchaser of grants by the Company to any person of rights to have their shares
of Common Stock participate in a Piggyback Registration.

                           (vii)    Preemptive Rights. Except for shares of the
Company's voting capital stock (the "Stock") issued in a public offering of
shares registered under the Securities Act, shares of Stock issued as
compensation or in conjunction with any employee benefit plan or program,
shares of Stock issued in connection with the conversion of the Debentures or
exercise of options or warrants, or shares of Stock issued for consideration
other than money (which, for purposes hereof, includes notes, bonds, debentures
or other similar debt instruments), in the event that the Company after the date
of this Agreement, but prior to August 31, 2000, issues any shares of Stock as a
new issue or from treasury (the "New Issue"), the Purchaser shall have the
pre-emptive right to purchase a percentage of such New Issue equal to the
Purchaser's percentage holding of the issued and outstanding Stock of the
Company at the date of such issuance. The Purchaser may exercise this
pre-emptive right at any time within fifteen (15) days after it receives written
notice from the Company of the contemplated offer, sale or issuance of the New
Issue, by delivery of a written notice stating the number of shares of the New
Issue it elects to so purchase and representing and warranting that the
Purchaser's representations and warranties to the Company set forth in Section 3
are true and correct in all material respects as though made on the date of such
notice.

                           (viii)   Subsidiary Stock.  The Company shall cause
its subsidiaries to not, and to require their subsidiaries to not, issue any
additional shares of capital stock of such subsidiaries, other than to (i) the
Company or (ii) a wholly owned subsidiary of either the Company or a wholly
owned subsidiary of the Company.

                  (b)      Company Board Covenant. So long as the Purchased
Shares owned by the Purchaser represent beneficial ownership of at least five
percent (5%) of the Common Stock of the Company, calculated in accordance with
the requirements of Section 13(d) of the Exchange Act, the Company agrees that,
as an inducement to the Purchaser to enter into this Agreement, a person
designated by the Purchaser shall be a member of the Company's Board of
Directors. The Company agrees that if such person is not a member of the
Company's Board of Directors as required by the foregoing sentence, except for
causes in the absolute control of Purchaser or the Purchaser's designee, such
circumstance shall be deemed to be a breach and violation of this Agreement by
the Company and the Purchaser shall have all remedies provided herein and at law
or in equity. A person designated by LCA or the LCA Group (as such terms are
defined in the Voting Agreement) pursuant to the Voting Agreement as their
designee for election to the Board of Directors of the Company shall be a person
designated by the Purchaser for purposes of this Section 8(b).

                  (c)      Purchaser Covenants.

                                       18
<PAGE>   19


                           (i)      NBD Subordination Agreement.  The Purchaser
agrees to negotiate with NBD Bank on the terms and conditions to be contained in
an agreement to be entered into at Closing between the Company, the Purchaser
and NBD Bank subordinating (A) the Purchaser's right to payment of a
Co-Marketing Termination Fee (as defined in the Security Agreement) to the
indebtedness and obligations due to NBD Bank from the Company and its
subsidiaries and (B) the Purchaser's security interest in certain assets of the
Company and its subsidiaries granted in the Security Agreement to the security
interest of NBD Bank in the same assets of the Company and its subsidiaries (the
"NBD Subordination Agreement"). The Purchaser agrees to enter into the NBD
Subordination Agreement at Closing, on terms mutually acceptable to the Company,
the Purchaser and NBD Bank, in their sole respective discretions.

         9.       Call of Common Stock.

                  (a)    At any time from October 1, 2000 to November 30, 2000
(the "Call Period"), the Company shall have the right, by written notice to the
Purchaser (the "Call Notice"), to purchase, all and not less than all, the
Purchased Shares then held by the Purchaser at a purchase price of $5.00 per
share (the "Call Price"). The "Call Effective Date" shall be the first business
day occurring more than thirty (30) days after the date the Purchaser receives
the Company's Call Notice. At the Call Effective Date, the Purchaser shall
deliver to the Company the certificates for the Purchased Shares, duly endorsed
in blank, in proper form for transfer, with all signatures properly guaranteed
by a member firm of the New York Stock Exchange or a commercial bank or trust
company that is a member of a signature guarantee medallion program, and the
Company shall deliver to the Purchaser the Call Price payable therefor in
immediately available funds.

                  (b)    At any time after termination of the Co-Marketing
Agreement in a manner which requires the Company to pay the Co-Marketing
Termination Fee, and upon the full payment of such fee to the Purchaser, the
Company shall have the right (the "Co-Marketing Agreement Call Right"), by
written notice to the Purchaser (the "Co-Marketing Call Notice"), to purchase,
all and not less than all, the Purchased Shares then held by the Purchaser at a
purchase price of $0.50 per share; provided that if the Co-Marketing Termination
Fee is not paid within 90 days after its due date the purchase price shall
increase to $0.75 per share and if the Co-Marketing Termination Fee is not paid
within 150 days after its due date the purchase price shall increase to $1.00
per share (the "Co-Marketing Call Price"). The "Co-Marketing Call Effective
Date" shall be the first business day occurring more than thirty (30) days after
the date the Purchaser receives the Company's Co-Marketing Call Notice. At the
Co-Marketing Call Effective Date, the Purchaser shall deliver to the Company the
certificates for the Purchased Shares, duly endorsed in blank, in proper form
for transfer, with all signatures properly guaranteed by a member firm of the
New York Stock Exchange or a commercial bank or trust company that is a member
of a signature guarantee medallion program, and the Company shall deliver to the
Purchaser the Co-Marketing Call Price payable therefor in immediately available
funds. During any period in which Universal is required to pay the Co-Marketing
Termination Fee, but in no event more than six (6) months after the due date of
the Co-Marketing Termination Fee (the "Restricted Period"), the Purchaser agrees
not to sell or transfer the Purchased Shares held by it. If the Co-Marketing Fee
is due and 


                                       19
<PAGE>   20


payable by the Company, but is not paid prior to the end of the Restricted
Period, then, after the end of the Restricted Period and until the Co-Marketing
Termination Fee is paid in full, the Purchaser may sell the Purchased Shares and
promptly following such sale the Company will pay the Purchaser an amount equal
to $4.00 per share times the number of shares of Purchased Shares actually so
sold, less the proceeds (net of selling commissions and discounts and expenses
incurred in connection with the sale) received by the Purchaser from the sale of
such shares of Purchased Shares.

                  (c)    Upon the occurrence of an Extraordinary Common Stock
Event, the Call Price and the Co-Marketing Call Price, respectively, shall,
simultaneously with the occurrence of such Extraordinary Common Stock Event, be
adjusted by multiplying the Call Price and the Co- Marketing Call Price,
respectively, in effect immediately before such Extraordinary Common Stock Event
by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately before such Extraordinary Common Stock Event and
the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such Extraordinary Common Stock Event and the
product so obtained shall thereafter be the Adjusted Call Price and the Adjusted
Co-Marketing Call Price, respectively. The Adjusted Call Price and the Adjusted
Co-Marketing Call Price, respectively, as so adjusted, shall be readjusted in
the same manner upon the occurrence of any subsequent successive Extraordinary
Common Stock Event or Events. "Extraordinary Common Stock Event" shall mean (i)
the issuance of additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, (ii) the subdivision of outstanding
shares of Common Stock into a greater number of shares of Common Stock, or (iii)
the combination of outstanding shares of Common Stock into a smaller number of
shares of Common Stock.

         10.      Registration Rights.

                  (a)    Demand Registration. At any time after July 1, 1999,
upon written request (a "Registration Request") of holders of a majority of the
Purchased Shares then subject to the registration rights provided for in this
Section 10(a) (who for purposes of this Section 10 shall be referred to
collectively as the "Purchaser"), the Company hereby agrees to file with the
Securities and Exchange Commission (the "SEC"), as soon as practicable
thereafter but not later than 30 days after receipt of such request, a
registration statement on Form S-3 or its successor form (the "Form S-3
Registration Statement"), registering the Purchased Shares then outstanding for
resale by the Purchaser. Upon receipt of the Registration Request, the Company
will give notice to all other holders of Purchased Shares then subject to the
registration rights provided for in this Section 10(a) of the Registration
Request (other than those making such request) (the "Other Purchasers"), and
offer to include in the Form S-3 Registration Statement Purchased Shares
(subject to the registration rights provided for in this Section 10) then held
by the Other Purchasers, and will include all such shares held by the Other
Purchasers in the Form S-3 Registration Statement which such Other Purchasers
elect, by a written notice to the Company within 15 days of their receipt of the
Company's notice. The Company will furnish the Purchaser with copies of the Form
S-3 Registration Statement prior to the filing of the same. The Company will use
its reasonable efforts

                                       20
<PAGE>   21


to have such Form S-3 Registration Statement declared effective promptly by the
SEC. The Company shall keep such Form S-3 Registration Statement effective for
the period necessary for the Purchaser to complete the public resale or other
disposition or distribution of the Purchased Shares or, if earlier, the date
when all of the Purchased Shares are eligible for sale in one 3-month period
under Rule 144 under the Securities Act. If in the good faith judgment of the
Board of Directors of the Company (as evidenced by an appropriately adopted
resolution), the filing, effectiveness or continued use of the Form S-3
Registration Statement would be materially detrimental to the Company and its
shareholders, then the Company shall have the right to defer such filing or
effectiveness, and may suspend the Purchaser's right to sell Common Stock under
the Form S-3 Registration Statement, for the period during which such filing,
effectiveness or use would be materially detrimental to the Company, provided
that such deferral or suspension shall be for a period of not more than sixty
(60) days and the Company shall not make such a deferral or suspension more than
once in any twelve month period, and, further provided, that during such
deferral or suspension the Company shall not file a registration statement for
securities to be issued and sold for its own account or for the account of any
other security holder of the Company, or both. The Company shall have the right
to defer the filing of the Form S-3 Registration Statement for a period of 180
days after the effective date of a registration statement, the preparation of
which the Company initiated at the time of the Purchaser's request for
registration. The Company shall not be required to file the Form S-3
Registration Statement on a date when the inclusion in such Form S-3
Registration Statement of financial statements of the Company, other than the
historical financial statements of the Company required to be contained in the
most recently required reports of the Company on SEC Forms 10-K and 10-Q and the
required reports on SEC Form 8-K since the end of the fiscal year covered by the
most recently required report on Form 10-K, would be required under the General
Rules and Regulations of the SEC.

                  (b) Piggyback Registration. Whenever the Company proposes to
register any of its securities under the Securities Act for sale by the Company
solely for cash (other than securities to be issued in connection with any
compensation plan, program or agreement), or, upon the request of any of its
shareholders who have contractual registration rights, for sale for the account
of any of its shareholders, other than Signal Capital Corporation ("Signal")
pursuant to the Original Stockholders Agreement, (an "Initiating Shareholder"),
(a "Piggyback Registration"), the Company will give written notice to the
Purchaser of its intentions to effect such a registration not later than the 20
days prior to the anticipated filing date. Before and after the Closing Date,
the Company will use its reasonable efforts to cause Signal to amend the
Original Stockholders Agreement to allow the Purchaser to piggyback on a
registration statement initiated by Signal in accordance with the provisions of
this Section 10(b) provided that the Company in doing so shall not be required
to provide Signal with any greater registration rights then those currently
provided under the original Stockholders Agreement. The Company will include in
such Piggyback Registration all of the Purchased Shares then subject to this
Agreement with respect to which the Company has received written request for
inclusion therein with 15 days after the receipt by the Purchaser of the
Company's notice. The Purchaser shall be permitted to withdraw all or any part
of the Purchased Shares from a Piggyback Registration at any time prior to the
effective date of such Piggyback Registration. If a Piggyback Registration is an
underwritten offering, the


                                       21
<PAGE>   22

Purchaser shall be obligated to sell its Purchased Shares on the same terms and
conditions as apply to the securities being issued and sold by the Company;
provided, however, that if an underwritten offering is being conducted in which
the Purchaser seeks to exercise its piggyback rights and the managing
underwriter advises the Company in writing that in its opinion the total number
or dollar amount of securities requested to be included in such registration
exceeds the number or dollar amount of securities which can be offered and sold
on reasonable terms and price under prevailing market conditions, the Company
will include in such registration first the securities which the Company
proposes to sell, if the registration was initiated by the Company, or the
securities which the Initiating Shareholders propose to sell, if the
registration was initiated by or for shareholders of the Company, and then the
remaining number and dollar amount of securities of the Company which, in the
opinion of the underwriter, can be sold shall be allocated among the Purchaser
and persons or entities, other than the Company and the Purchaser, with
contractual registration rights seeking to include their securities of the
Company in the registration statement (the "Other Holders") (collectively, the
Purchaser and the Other Holders shall be referred to as the "Selling Holders")
and, in the case where the registration was initiated by or for Initiating
Shareholders, the Company, in proportion to the number of shares of Common Stock
or other securities each such person has elected to include in the registration
statement.

         Notwithstanding the foregoing, if the Company proposes to sell any of
its securities under the Securities Act pursuant to the terms of warrants,
rights or convertible securities which are being registered in connection with
the registration of such warrants, rights or convertible securities or in
connection with dividend reinvestment plans, the Company shall have no
obligation to register Purchased Shares for sale as part of the offering of such
warrants, rights or convertible securities unless the Purchased Shares can be
registered and sold in an offering conducted subsequent to such offering, and
provided that if the managing underwriter or their representatives, or the
selling dealers or their representatives, if any, determine, reasonably and in
good faith that the number of securities in any such registration exceeds the
number of shares which can be offered and sold on reasonable terms and price
under prevailing market conditions, the Company will include in such
registration first the warrants, rights or convertible securities which the
Company proposes to sell and then, in a subsequent offering, the number and
dollar amount of Common Stock or other securities of the Company which can be
sold under prevailing market conditions, reduced, if necessary, on a
proportionate basis among such Selling Holders as described above.

         Nothing in this Section 10(b) shall be deemed to require the Company to
proceed with any registration of its securities after giving the notice herein
provided.

                  (c)   Blue Sky. The Company shall use its reasonable efforts
to register or qualify the Purchased Shares under such securities acts or laws
of such states of the United States as the Purchaser shall reasonably request;
provided, however, that in no event shall the Company be obligated, in
connection therewith, to qualify to do business in any jurisdiction where it
shall not then be qualified, grant a general consent to service of process in
any jurisdiction in which such

                                       22
<PAGE>   23

consent to service has not been previously given or subject itself to taxation
in any jurisdiction where it is not then subject to taxation.

                  (d)    Additional Obligations.  The Company hereby agrees to:

                         (i)      Supply to the Purchaser one true copy of each
Form S-3 Registration Statement and each registration statement filed in
connection with a Piggyback Registration (collectively, the "Registration
Statement") (and any supplement or amendment thereto) and such number of the
preliminary, final and any other prospectus and amendments thereto, prepared in
conformity with the requirements of the Securities Act and the rules and
regulations thereunder, as each such Purchaser may reasonably request in order
to facilitate the public sale of shares owned by the Purchaser.

                         (ii)     Remove all "stop transfer orders" relating 
to the Purchased Shares once registered with the SEC under Section 5 of the
Securities Act and, thereafter, remove all legends from stock certificates
representing such Purchased Shares restricting the transferability of such stock
under applicable securities laws;

                         (iii)    Notify the Purchaser immediately, and
confirm the notice in writing, (A) of the effectiveness of the Registration
Statement and any amendment thereto (including any post-effective amendment),
(B) of the receipt of any comments from the SEC, (C) of any request by the SEC
for any amendment to the Registration Statement or any amendment or supplement
to any prospectus relating thereto or for additional information, (D) of the
issuance by the SEC of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose and
(E) immediately notify the Purchaser at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event as a result of which the prospectus included in such Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or incomplete in the light of the
circumstances then existing. The Company will use its best efforts to prevent
the issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

                         (iv)     Give the Purchaser notice of its intention
to file or prepare any amendment to the Registration Statement (including any
post-effective amendment) or any amendment or supplement to the final prospectus
(including any revised prospectus which the Company proposes for use by the
Purchaser in connection with the offering of the Purchased Shares which differs
from the prospectus on file at the SEC at the time the Registration Statement
becomes effective, whether or not such revised prospectus is required to be
filed pursuant to Rule 424(b) of the Securities Act Regulations), and furnish
the Purchaser with copies of any such amendment or supplement a reasonable
amount of time prior to such proposed filing or use, as the case may be. The
term "Prospectus" shall refer to the final prospectus and any revised prospectus
provided to the Purchaser from time to time thereafter and all material
incorporated by reference



                                       23
<PAGE>   24

therein. The Company shall prepare and file with the SEC all amendments and
supplements to the Registration Statement and Prospectuses necessary to comply
with the Securities Act and to keep the Registration Statement effective as
required by Section 10(a) in the case of a Form S-3 Registration Statement and
Section 10(b) in the case of a Piggyback Registration.

                           (v)      Amend or supplement the Prospectus forthwith
if any event shall occur as a result of which it is necessary to amend or
supplement the Prospectus in order to make the Prospectus not misleading in the
light of the circumstances existing at the time it is delivered to a purchaser,
so that, as so amended or supplemented, the Prospectus will not include an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances
existing at the time it is delivered to a purchaser, not misleading, and furnish
to the Purchaser such copies of such amendment or supplement as Purchaser shall
request.

                           (vi)     Make available to its security holders, as
soon as reasonably practicable, an earnings statement covering the period of at
least twelve months, but not more than eighteen months, beginning with the first
month after the effective date of the Registration Statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act;
and

                           (vii)    Take such other actions as are reasonably
requested by the Purchaser in connection with the registration of the Purchased
Shares pursuant to this Section 10.

                           (viii)   Use its reasonable efforts to cause all
Purchased Shares covered by such Registration Statements described in this
Section 10 to be listed on Nasdaq, if the Common Stock of the Company is then
listed on Nasdaq, or any securities exchange on which the Common Stock of the
Company is then listed.

                  (e)      Expenses of Registration. All expenses, other than
underwriting discounts and selling commissions, incurred in effecting any
registration pursuant to this Section 10, including, without limitation, all
costs of preparation and registration, filing fees, printing expenses, expenses
of compliance with Blue Sky laws, fees and disbursements of counsel for the
Company and fees and disbursements of counsel for the Purchaser, up to a maximum
of $20,000.00 for Purchaser's counsel, shall be borne by the Company; provided
that, in connection with any Piggyback Registration, the Purchaser shall bear
the cost of additional filing fees, printing costs and Blue Sky fees and
expenses resulting from the inclusion of the Purchased Shares in such
registration in proportion to the relative amounts of Purchased Shares included
by the Purchaser in such Piggyback Registration in relation to all shares of
Common Stock included in such Piggyback Registration by shareholders of the
Company.

                  (f)      Conditions to Company's Obligations. The Company's
obligations under this Section 10 shall be conditioned upon a timely receipt by
the Company (after the Company's


                                       24
<PAGE>   25

delivery of notice requesting the same and providing for a reasonable response
period) in writing of:

                           (i)      Information as to the terms of such public
offering furnished by or on behalf of the Purchaser; and

                           (ii)     Such other information as the Company may
reasonably require from the Purchaser for inclusion in such Registration
Statement.

                  (g)      Indemnification.

                           (i)      The Company agrees to indemnify and hold
harmless the Purchaser, its directors, officers and employees and each person,
if any, who controls the Purchaser within the meaning of Section 15 of the
Securities Act, against any and all loss, liability, claim, damage and expense
whatsoever (including court costs and attorneys' fees) arising out of any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (or any amendment or supplement thereto), including the
information deemed to be part of the Registration Statement pursuant to Rule
430A of the rules and regulations of the SEC under the Securities Act (the
"Securities Act Regulations"), if applicable, or the omission or alleged
omission therefrom of a material fact required to be stated therein or necessary
to make the statements therein not misleading or arising out of any untrue
statement or alleged untrue statement of a material fact contained in any
Prospectus (or any amendment or supplement thereto) or the omission or alleged
omission therefrom of a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading or any violation by the Company of any applicable securities law or
regulation or any action brought by the Purchaser to enforce this
indemnification; provided, however, that this indemnity agreement shall not
apply to any loss, liability, claim, damage or expense to the extent (i) arising
out of any untrue statement or omission or alleged untrue statement or omission
made in reliance upon and in conformity with written information furnished to
the Company by the Purchaser expressly for use in the Registration Statement (or
any amendment or Supplement thereto) or any Prospectus (or any amendment or
supplement thereto) or (ii) arising from the fact that a copy of the Prospectus
was not timely delivered by the Purchaser to a purchaser who became a plaintiff
in a lawsuit.

                           (ii)     The Purchaser agrees to indemnify and hold
harmless the Company, its directors, each of its officers who signed the
Registration Statement, officers and employees and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section, as incurred, but only
with respect to untrue statements or omissions made in the Registration
Statement (or any amendment thereto) or any  Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
to the Company by the Purchaser for use in the Registration Statement (or any
amendment thereto) or such final Prospectus (or any amendment or supplement
thereto) or any


                                       25
<PAGE>   26

violation by the Purchaser of any applicable securities law or regulation or any
action brought by the Company to enforce this indemnification.

                           (iii)    Each indemnified party shall give notice as
promptly as reasonably practicable to each indemnifying party of any action
commenced against it in respect of which indemnity may be sought hereunder, but
failure to so notify an indemnifying party shall not relieve such indemnifying
party from any liability which it may have otherwise than on account of this
indemnity agreement. In case such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate in, and, to the extent that
it may wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such
indemnified party of its election to assume the defense thereof and so long as
the indemnifying party continues to defend vigorously and in good faith the
matter, the indemnifying party shall not be liable under this indemnity for any
legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof, provided however, that the indemnified party shall
have the right to employ separate counsel at its expense in any such action and
participate in the defense thereof. No indemnifying party shall be liable for
any settlement entered into without its consent. No indemnifying party shall,
except with the written consent of the indemnified party, consent to the entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant to the indemnified party
of a release from all liability concerning the claim. An indemnifying party who
elects not to assume the defense of a claim will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by the
indemnifying party with respect to the claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between the
indemnified party and any other indemnified party with respect to the claim, in
which event the indemnifying party shall be obligated to pay the fees and
expenses of such additional counsel to defend such indemnified party having a
conflict of interest with another indemnified party, provided that the Company
shall not be required to pay for more than one additional counsel per venue for
all such indemnified parties having a similar conflict of interest with such
other indemnified party, unless they have conflicts of interest among themselves
with respect to the claim, in which case, the indemnifying party shall be
required to pay for one additional counsel per venue for each such indemnified
party which has a conflict of interest.

                  (h)      Contribution. If the indemnification provided for in
Section 10(g) is unavailable to an indemnified party in respect of any losses,
liabilities, claims, damages, or expenses referred to therein, then each
indemnifying party thereunder shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, liabilities, claims, damages
or expenses in such proportion as is appropriate to reflect the relative fault
of the Company and the Purchaser in connection with the statements or omissions
that resulted in such losses, liabilities, claims, damages or expenses, as well
as any other relevant equitable considerations. The relative fault of the
Company and the Purchaser shall be determined by reference to, among other
things, whether the untrue or alleged statement of a material fact or the

                                       26
<PAGE>   27

omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Purchaser and the parties' relative intent and
knowledge.

                           The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 10(h) were determined by
pro rata allocation or by any other method of allocation that does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. For purposes
of this Section, each director of the Purchaser, each officer of the Purchaser
and each person, if any, who controls the Purchaser within the meaning of
Section 15 of the Securities Act shall have the same rights to contributions as
such Purchaser, and each director of the Company, each officer of the Company
who signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Company.

                  (i)      Survival. The indemnification provided in this
Section 10 shall survive the registration and sale of the Purchased Shares by
the Purchaser and the expiration or termination of this Agreement.

                  (j)      Transfers. The rights granted to the Purchaser by the
Company under this Section 10 may be transferred or assigned by the Purchaser
only to a transferee or assignee of 285,000 or more of the Purchased Shares (as
presently constituted and subject to subsequent adjustments for stock splits,
stock dividends, reverse stock splits, and the like), provided that the Company
is given written notice at the time of or within a reasonable time after said
transfer or assignment, stating the name and address of the transferee or
assignee and, provided further, that the transferee or assignee of such rights
assumes the obligations of Purchaser under this Section 10. The Purchased Shares
are no longer covered by the provisions of this Section 10 once sold in a
registered public offering or in accordance with the requirements of Rule 144
under the Securities Act or other similar provision.

                  (k)      Rule 144 Reporting. The Company agrees to make and
keep public information available, as those terms are understood and defined in
Rule 144 of the Securities Act, at all times after the date of this Agreement.
The Company further agrees to use its best efforts to file with the SEC in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act. So long as the Purchaser owns Purchased
Shares, the Company agrees to furnish promptly to the Purchaser, upon its
reasonable request, a written statement by the Company as to its compliance
with reporting requirements of said Rule 144 and of the Securities Act and the
Exchange Act, a copy of the most recent annual or quarterly financial
statements of the Company and such other reports and documents so filed with
the SEC by the Company which will allow the sale of any such Purchased Shares
under Rule 144 without registration. 

         11.      Indemnification.

                                       27
<PAGE>   28


                  (a)      Indemnification by Purchaser. The Purchaser hereby
agrees to indemnify, defend and hold harmless the Company, its officers,
directors, employees, shareholders, agents and its successors and assigns,
against any and all liabilities, obligations, losses, damages, demands, claims,
assessments, actions, tax deficiencies, penalties and interest, reasonable
accounting and attorneys' fees, costs and expenses (individually a "Loss" and
collectively "Losses"), arising out of, or incident to, any of the following:

                           1.       Any misrepresentation, or breach of any
                                    warranty of Purchaser contained in this
                                    Agreement.


                           2.       Any breach of any covenant, agreement or
                                    other term or provision hereof to be
                                    performed by Purchaser.

                  (b)      Indemnification by the Company. The Company hereby
agrees to indemnify, defend and hold harmless the Purchaser, its officers,
directors, employees, shareholders, agents and its successors and assigns,
against any and all liabilities, obligations, losses, damages, demands, claims,
assessments, actions, tax deficiencies, penalties and interest, reasonable
accounting and  attorneys' fees, costs and expenses (individually a "Loss" and
collectively "Losses"), arising out of, or incident to, any of the following:

                           1.       Any misrepresentation, or breach of any
                                    warranty of the Company contained in this
                                    Agreement.

                           2.       Any breach of any covenant, agreement or
                                    other term or provision hereof to be
                                    performed by the Company.

                  (c)      Claims. If either party desires to make a claim
against the other under Section 11(a) or (b) hereof which does not involve a
claim by any person other than the parties, then such party shall make such
claim by promptly delivering notice to the other in the form set forth in (1)
below. If either party (the "Claimant") desires to make a claim for indemnity
against the other (the "Indemnitor") under this Agreement which involves a
demand, claim or threat of litigation or the actual institution of any action,
suit or proceeding (collectively, a "Claim") by a person other than the
parties, then such Claim will be made in the following manner and be subject to
the following terms and conditions unless otherwise provided for in this
Agreement:

                           Each Claimant shall give notice as promptly as
reasonably practicable to each Indemnitor of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
Indemnitor shall not relieve such Indemnitor from any liability which it may
have otherwise then on account of this Section 11. In case such action is
brought against any Claimant, and it notifies the Indemnitor of the
commencement thereof, the Indemnitor will be entitled to participate in,
and, to the extent that it may wish, jointly with any Indemnitor similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory
to such Claimant and after notice from the Indemnitor to such Claimant of its
election to assume


                                       28
<PAGE>   29

the defense thereof and so long as the Indemnitor continues to defend vigorously
and in good faith the matter, the Indemnitor shall not be liable under this
indemnity for any legal expenses subsequently incurred by such Claimant in
connection with the defense thereof, provided however, that the Claimant shall
have the right to employ separate counsel at its expense in any such action and
participate in the defense thereof. No Indemnitor shall be liable for any
settlement entered into without its consent. No Indemnitor shall, except with
the written consent of the Claimant, consent to the entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant to the Claimant of a release from all
liability concerning the claim. Any Indemnitor who elects not to assume the
defense of a claim will not be obligated to pay the fees and expenses of more
than one counsel for all parties indemnified by the Indemnitor with respect to
the claim, unless in the reasonable judgment of any Claimant a conflict of
interest may exist between the Claimant and any other indemnified party with
respect to the Claim, in which event the Indemnitor shall be obligated to pay
the fees and expenses of such additional counsel to defend such Claimant having
a conflict of interest with another indemnified party, provided that the
Indemnitor shall not be required to pay for more than one additional counsel per
venue for all such indemnified parties having a similar conflict of interest
with such other indemnified party, unless they have a conflict of interest among
themselves with respect to the Claim, in which case, the Indemnitor shall be
required to pay for one additional counsel per venue for each such Claimant
which has a conflict of interest.

                  (d)    Mitigation of Losses. A Claimant shall be entitled to
recover the full amount of any Losses incurred due to the matter for which
indemnification is sought, including reasonable attorney's fees incurred in
connection therewith, but any recovery shall be net of (a) any insurance
proceeds, or (b) any payments received from third parties relating to the
matter.

         12.      Governing Law and Time. This Agreement shall be governed by
and construed in accordance with the laws of the State of Michigan applicable to
agreements made and to be performed in said State (without regard to its choice
of law or conflict of law rules). The Company hereby consents to the personal
jurisdiction of the federal courts (or, if any such federal court is without
jurisdiction, a state court) located in or including Burlington, North Carolina
in connection with any controversy related to this Agreement and waives any
argument that venue in any such forum is not convenient.

constitute a part of this Agreement for any other purpose.

counterparts, each of which shall be deemed an original, but all of which 
together shall constitute one and the same instrument.

         15.      Assignment. This Agreement may not be assigned by either party
hereto without the prior written consent of the other party hereto.

obtains the written consent of the Purchaser. No failure to exercise and no
delay in exercising any right under this Agreement shall operate as a waiver on
such right. No exercise or partial exercise of any right granted under this
Agreement shall preclude any other or further exercise thereof or the exercise
of any other right. The rights and remedies provided in this Agreement are
cumulative and are not exclusive of any other rights or remedies provided by
law.
