               ability to perform certain services as it relates to the
               potential relationship between the parties referenced above.
               Specifically, UAB shall perform and determine the three
               dimensional structures of said MATERIAL (hereinafter "PURPOSE").

          2.   ATHERSYS hereby grants to UAB a nonexclusive license to the

               performance of the services under this Agreement does not
               transfer to UAB any right, title or interest in the MATERIAL.
               Specifically, title to the MATERIAL shall remain in ATHERSYS and
               transfer of said MATERIAL by ATHERSYS is to be considered a
               bailment for purposes of this Agreement and not a conditional or
               unconditional sale.

          3.   The MATERIAL shall not be used in any research that is subject to
               any consulting or license agreement with or sponsored by any
               third party without the prior written consent of ATHERSYS. The
               MATERIAL shall not be commingled with any biological material(s),

               consent of ATHERSYS.

          4.   UAB may not assign, sublicense, transfer or convey any rights
               established in this Agreement to any third party, other than the
               UAB Research Foundation (UABRF), without the prior written
               consent of ATHERSYS and any such assignment, sublicensing, or
               transfer without ATHERSYS' consent shall be void. UAB may not
               assign, sublicense, transfer or convey any rights established in
               the MATERIAL to any third party without the prior written consent
               of ATHERSYS and any such assignment, sublicensing, or transfer
               without ATHERSYS' consent shall be void. UABRF may not assign,
               sublicense, transfer or convey any rights established in this
               Agreement or the MATERIALS to any third party, without the prior
               written consent of ATHERSYS and any such assignment,
               sublicensing, or transfer without ATHERSYS' consent shall be
               void.

               Dr. DeLucas without the prior written consent of ATHERSYS.

          7.   UAB, if required by ATHERSYS, will pay all costs of
               transportation of the MATERIAL from ATHERSYS to UAB and, if
               necessary, costs of transporting unused MATERIAL from UAB back to
               ATHERSYS.

          8.   Upon the termination of this Agreement, as provided herein below,
               UAB will return all the MATERIAL to ATHERSYS within ten (10) days
               of the termination date.

          9.   UAB agrees that it will provide the results of its research
               utilizing the MATERIAL to ATHERSYS, including copies of all
               articles, abstracts, and any written information, et cetera,
               reporting or utilizing the results of all research by UAB using
               the MATERIAL.

          10.  UAB shall not publish or disclose to others the results of
               research using the MATERIAL without submitting the proposed
               publication or disclosure to ATHERSYS at least thirty (30) days
               prior to submission for publication or disclosure to allow
               ATHERSYS to review the matter for disclosure of ATHERSYS
               proprietary information.

          11.  UAB agrees to use the MATERIAL in compliance with all applicable
               federal, state or local statutes and regulations as well as in
               compliance with all UAB applicable policies, rules and
               regulations that UAB may revise, amend or delete solely at its
               discretion

III. DISPOSITION OF INTELLECTUAL PROPERTY ARISING FROM THIS AGREEMENT:

          If UAB's research results in an invention, new use or a product based
     on, containing, or relating to the MATERIAL ("Invention"), UAB will
     promptly disclose the Invention to ATHERSYS. Title to any subject matter of
     any patent or patent application generated or developed through the use of
     this MATERIAL shall be governed by the rules of United States Inventorship
     provided that ATHERSYS shall have first right to negotiate an exclusive
     license to any invention conceived in part or whole by UAB ("UAB
     Invention") for a period of

                                       3

     unable to come to terms during the initial six (6) month period, UAB will
     be free to negotiate a license covering a UAB Invention to a third party
     ("Third Party Offer"), provided that ATHERSYS will retain a first right of
     refusal to match the terms of any such Third Party Offer, such first right
     of refusal to be exercised within thirty (30) days of presentation of Third
     Party Offer to ATHERSYS by UAB in writing.

     B.   In no event shall UAB be liable for any use of the MATERIAL or
          generated data. ATHERSYS hereby agrees to defend, indemnify, and hold
          harmless UAB and its trustees, employees, staff, and agents against
          any claims, losses, demands or liability, of whatsoever kind or
          nature, which may arise from or in connection with UAB's acceptance of
          the MATERIAL including the use, handling, storage, or research to be
          conducted with the MATERIAL by UAB; provided that ATHERSYS shall have
          no obligation to indemnify UAB for negligent acts or willful

     D.   It is further understood and agreed that no failure or delay by either
          party in exercising any right, power or privilege under this Agreement

                               II. PURCHASE PRICE

         2.1. Purchase Price. In addition to assuming the Assumed Liabilities

price in the amount of $10,000,000 subject to adjustment as provided in Sections

("NOTE B"), having such terms and conditions as set forth in the Credit
Agreement and in the form attached hereto as Exhibit B (Note A together with
Note B, the "NOTES"). At the Closing, the Deposit will be applied as a credit to
the Purchase Price.

         2.2. Utility Deposit Proration. A list of all security deposits,
escrows, utility deposits and other deposits of a similar nature (collectively,
the "PREPAID DEPOSITS") of Seller in respect of the Business shall be provided
by Seller to Purchaser on the Closing Date (the "DEPOSIT CERTIFICATE").
Purchaser shall pay to Seller on the Closing Date the aggregate amount of all
items shown on the Deposit Certificate and the Prepaid Deposits reflected on the
Deposit Certificate shall be included in the Assets.

         2.3. Net Accounts Receivable Adjustment.

                  2.3.1. As used in this Agreement, "NET ACCOUNTS RECEIVABLE"
means: (a) 80% of the face amount of all Accounts Receivable existing at the
Closing (excluding all Accounts Receivable with a due date earlier than the 90th
day prior to the Closing) minus (b) the minimum amount that would be required to
be accrued on the face of a balance sheet of Seller as of the Closing prepared
in accordance with Generally Accepted Accounting Principals ("GAAP") (a "CLOSING
BALANCE SHEET") for trade accounts payable of Seller included in the Assumed
Liabilities.

                  Within 90 days following the Closing, Purchaser will prepare
(under the observation of Seller or Seller's designee) and will provide Seller
with a calculation of Net Accounts Receivable. Following the preparation of the
Net Accounts Receivable calculation, Purchaser and Seller will in good faith
work to promptly agree on a final calculation of Net Accounts Receivable.

                  2.3.2. If Seller disagrees with Purchaser's calculation of Net
Accounts Receivable, Seller may, within 30 days (the "OBJECTION PERIOD") after
the delivery to Seller by Purchaser of the Net Accounts Receivable calculation,
deliver a notice (the "OBJECTION NOTICE") to Purchaser disputing such
calculation and setting forth Seller's calculation thereof. Any Objection Notice
shall, to the extent reasonably practicable, specify in reasonable detail those
items or amounts as to which Seller disagrees and the basis for disagreement.
Except with respect to the items set forth in the Objection Notice and items
affected by the disputed items, Seller shall be deemed to have agreed with all
other items and amounts contained in Purchaser's Net Accounts Receivable
calculation.

                                        4
<PAGE>   10
                  2.3.3. If an Objection Notice shall be properly and timely
delivered, Purchaser and Seller shall cause the Los Angeles office of
PricewaterhouseCoopers LLP (or, if they are unable or unwilling to serve, a firm
of independent accountants of nationally recognized standing reasonably
satisfactory to Purchaser and Seller (which shall not have any material
relationship with Purchaser or Seller)) (the "ACCOUNTANTS") to promptly review
this Agreement and the disputed items or amounts for the purpose of calculating
the final Net Accounts Receivable. In making such calculation, the Accountants
shall consider only those items or amounts in Purchaser's calculation of Net
Accounts Receivable as to which Seller has, in the Objection Notice, disagreed
and such other issues as may reasonably be affected by the items as to which
Seller has disagreed. The Accountants shall deliver to Purchaser and Seller, as
promptly as practicable, a written report setting forth their calculation of the
disputed items. Absent manifest error, such report shall be final and binding
upon Purchaser and Seller. The cost of such review and report shall be divided
equally between Purchaser and Seller.

                  2.3.4. Each of Purchaser and Seller will cooperate and assist
in the preparation of the Net Accounts Receivable calculation and in the conduct
of the reviews referred to in this Section 2.3, including, without limitation,
(a) Purchaser making available to the extent reasonably necessary or helpful any
books, records and personnel relating to the Assets, the Accounts Receivable and
trade accounts payable included in the Assumed Liabilities or the Business and
(b) Seller making available to the extent reasonably necessary or helpful any
books, records and personnel of Seller.

                  2.3.5. Within 30 days following the determination of Net
Accounts Receivable, Seller will pay Purchaser an amount equal to the amount by
which, if any, Net Accounts Receivable are less than $0.00.

         2.4. Timing of Adjustments. All adjustments to the Purchase Price will
be calculated as of 11:59 p.m. on the Closing Date.

         2.5. Allocation of Purchase Price. The Purchase Price represents the
amount agreed upon by Purchaser and Seller to be the aggregate fair market value
of the Assets. Purchaser and Seller have agreed that the Purchase Price will be
allocated among the Assets in the manner set forth in Schedule 2.5. Purchaser
and Seller will allocate the Purchase Price to the Assets in such manner
consistently for all purposes, including in connection with all federal,
foreign, state, local and other Tax Returns (as defined herein) and reports
prepared and filed by or for either of Purchaser or Seller.

                         III. ASSUMPTION OF LIABILITIES

         3.1. Assumed Liabilities. Subject to Section 3.2 hereof, as of the

         3.2. Retained Liabilities. Seller will retain, and Purchaser will not

that relate to long-term or short-term bank debt obligations of Seller, any
Taxes that are income Taxes, or any Taxes due prior to the Closing Date

Delaware. Seller is duly qualified to conduct business as a foreign corporation
in each other jurisdiction in which its ownership or lease of property or
conduct of the Business requires such qualification under applicable Laws.

                  4.1.2. Authorization and Effect of Agreement. Seller has the
requisite corporate power to execute and deliver this Agreement and to perform
the transactions contemplated by this Agreement to be performed by Seller. The

have been duly authorized by all necessary action on the part of Seller. This
Agreement has been duly executed and delivered by Seller and, assuming the due
execution and delivery of this Agreement by Purchaser, constitutes a valid and
binding obligation of Seller enforceable in accordance with its terms except as
such enforceability may be limited by bankruptcy, insolvency, reorganization or
other similar laws affecting the enforcement of creditors' rights generally.

                  4.1.3. No Restrictions Against Sale of the Assets. Except as
set forth on Schedule 4.1.3, to Seller's knowledge, the execution and delivery
of this Agreement by Seller does not, and the performance by Seller of the
transactions contemplated hereby to be performed by it will not, conflict with,
or result in any violation of, or constitute a default under, or give rise to a
right of termination, cancellation or acceleration of any Assumed Contract,
except where such conflict, violation, default, termination, cancellation or
acceleration would not have a material adverse effect on the continued conduct
of the Business or Purchaser's use of the Acquired Assets or the Property To Be
Leased (collectively, the "TOTAL ASSETS") taken as a whole ("MATERIAL ADVERSE
EFFECT"). To Seller's knowledge, no consent, approval, order or authorization
of, or registration, declaration or filing with, any Governmental Entity is
required to be obtained or made by or with respect to Seller under any
applicable Law in connection with the execution and delivery of this Agreement
by Seller or the performance by Seller of the transactions contemplated hereby
to be performed by it, except where the failure to obtain or

                                        6
<PAGE>   12
make such consent, approval, order, authorization, resolution, declaration or
filing would not have a Material Adverse Effect.

                  4.1.4. Compliance With Laws. Except as described on Schedule
4.1.4, to Seller's knowledge Seller has complied with all Laws applicable to it,
except where the failure to be in compliance would not have a Material Adverse
Effect. Except as set forth on Schedule 4.1.4, Seller has not received any
written notice of any violation of any Law, or any potential liability under any
Law, which violation or liability would have a Material Adverse Effect.

                  4.1.5. Accounts Receivable. The Accounts Receivable are
ordinary trade receivables that have arisen from bona fide transactions in the
Ordinary Course. To Seller's knowledge, the Accounts Receivable are not subject
to any presently existing claim of offset or rebate.

                  4.1.6. Tangible Personal Property.

                  (a) Seller has marketable title to the Owned Tangible Personal
Property, and the Owned Tangible Personal Property is free and clear of all
liens, mortgages, security interests, preemptive purchase rights or other
similar encumbrances (collectively, "LIENS"), except for Permitted Tangible
Personal Property Liens (as defined herein) and any additional Liens listed or
described in Schedule 4.1.6.

                  (b) The delivery to Purchaser at Closing of the instruments of
Transfer contemplated by this Agreement will vest in Purchaser title to the

Schedule 4.1.6 and marked with an "*" (the Liens described in the foregoing
clauses (i) and (ii) being collectively referred to herein as "PERMITTED
TANGIBLE PERSONAL PROPERTY LIENS").

                  (c) To Seller's knowledge, the Owned Tangible Personal
Property is in working order, reasonable wear and tear excepted.

                  4.1.7. Leased Real Property. The Property To Be Leased

conduct of the Business. Except as described on Schedule 4.1.7(a), Seller has
not sublet, as sublessor, and no third party is in possession of, any of the
Property To Be Leased. The real property lease (the "REAL PROPERTY LEASE"), a
copy of which is attached hereto as Schedule 4.1.7(b) pursuant to which Seller
leases the Property To Be Leased is, to Seller's knowledge, in full force and
effect and no default on the part of Seller exists.

                  4.1.8. Intellectual Property. (a) Schedule 4.1.8 lists or
describes all material registered patents, copyrights, trademarks, trade names,
service marks and applications therefor used in the conduct of the Business

the rules of any national stock exchange applicable to it or its Affiliates, in
which event the party making such determination will, if practicable in the

         "10b-5" representation and a representation that Circuit Research Labs,
         Inc. has terminated its listing agreement with the National Association
         of Securities Dealers.

                           (5) Certificate of Insurance. A certificate of
         insurance evidencing insurance on the Assets and the Collateral (as
         defined in the Guaranty and Collateral Agreement) of the type required
         by the Credit Agreement and the Guarantee and Collateral Agreement and
         in amounts reasonably satisfactory to Seller.

         6.5. Termination. Notwithstanding anything contained in this Agreement
to the contrary, this Agreement may be terminated at any time prior to the
Closing:

                  (a) By the mutual written consent of Seller and Purchaser;

                  (b) By Seller on or after June 15, 2000 by written notice to
Purchaser if any of the conditions to the obligations of Seller contained in
this Agreement have not been satisfied or, if unsatisfied, have not been waived
in writing by Seller on or prior to June 15, 2000;

                  (c) By Purchaser on or after June 15, 2000 by written notice
to Seller if any of the conditions to the obligations of Purchaser contained in
this Agreement have not been satisfied or, if unsatisfied, have not been waived
in writing by Purchaser on or prior to June 15, 2000;

                  (d) By Seller or Purchaser if there will have been entered a
final, nonappealable order or injunction of any Governmental Entity restraining
or prohibiting the consummation of the transactions contemplated hereby or any
material part thereof; and

                  Except as provided in the next sentence, in the event of
termination of this Agreement under this Section 6.5, there will be no further
liability hereunder on the part of any party hereto if this Agreement is so
terminated, except for obligations of the parties hereto under Article VIII and
Sections 9.2 and 9.9 which shall survive termination of this Agreement. Nothing
in this Section 6.5 shall, however, relieve either party to this Agreement of
liability for breach of this Agreement occurring prior to such termination, or
for breach of any provision of this Agreement which specifically survives
termination hereunder.

                           VII. REPURCHASE TRANSACTION

         If, as of the six month anniversary of the Closing Date Purchaser has
not paid in full the Note B, Seller may, in its sole discretion, rescind the
transactions contemplated by this Agreement and the parties to this Agreement
will, subject to the terms of this Article VII, be restored, to the greatest
extent possible, to their respective positions of ownership as existed
immediately prior to the consummation of this Agreement. If Seller exercises its
option under this Article VII to rescind the transactions contemplated by this
Agreement, Seller will return the Purchase Price to Purchaser, less $750,000
which will be retained by Seller as liquidated damages to compensate Seller for
the failure of Purchaser to satisfy the covenant contained in Section 5.13 and
the costs, expenses and losses, including lost profits, incurred or that will be
incurred as a result of Seller having to rescind the transactions contemplated
by this Agreement, which costs, expenses and losses the parties hereto agree are
difficult, if not impossible to predict or calculate. Upon exercise by Seller of
its option under this Article VII to rescind, Purchaser

                                       18
<PAGE>   24
shall transfer the Assets (except to the extent sold in the Ordinary Course)
together with all contracts, accounts receivables and inventories of the
Business, with the accounts receivable and inventory each being at levels not
less than the levels delivered by Seller to Purchaser at the Closing. Seller
will have the right, but not the obligation, to hire all employees employed in
the Business and Purchaser will make representations to Seller about the Assets,
contracts, accounts receivable, and inventory and the Business comparable to
those given by Seller to Purchaser in this Agreement. Seller will not be
obligated to assume any liabilities of the Business. Purchaser and Seller agree
to execute all necessary or desirable instruments, certificates or agreements to
facilitate the performance of, and as near as possible effect the meaning of,
this article VII.

                       VIII. SURVIVAL AND INDEMNIFICATION

         8.1. Survival of Representations, Warranties and Covenants. The
representations and warranties of the parties contained in this Agreement will
be deemed to have been made on the date of this Agreement and on the Closing
Date will survive the Closing Date and will remain operative and in full force
and effect for a period of one year from the Closing Date.

         8.2. Indemnification by Purchaser. From and after the Closing,
Purchaser will indemnify, defend and hold Seller, its Affiliates, and their
respective directors, officers, representatives, employees and agents harmless
from and against any and all claims, actions, suits, demands, assessments,
judgments, losses, liabilities, damages, costs and expenses (including interest,
penalties, attorneys' fees, accounting fees and investigation costs)
(collectively, "LIABILITIES") resulting or arising from, relating to or incurred
in connection with: (a) any failure of Purchaser to pay, perform and discharge
any of the Assumed Liabilities, (b) any material breach of any representation or
warranty of Purchaser contained in this Agreement, (c) any material breach of
any covenant of Purchaser contained in this Agreement, (d) actions of Purchaser,
its employees and agents under Section 5.1 or (e) the termination of any
Employee by Purchaser from and after the Closing.

         8.3. Indemnification by Seller. From and after the Closing, Seller will
indemnify, defend and hold Purchaser, its Affiliates, and their respective
directors, officers, representatives, employees and agents harmless from and
against any and all Liabilities resulting or arising from, relating to or
incurred in connection with: (a) any failure of Seller to pay, perform and
discharge any of the Retained Liabilities, (b) any material breach of any
representation or warranty of Seller contained in this Agreement, (c) any
material breach of any covenant of Seller contained in this Agreement.

         8.4. Notice of Claim; Right to Participate in and Defend Third Party
Claim.

                  (a) If any indemnified party receives notice of the assertion
of any claim, the commencement of any suit, action or proceeding, or the
imposition of any penalty or assessment by a third party in respect of which
indemnity may be sought hereunder (a "THIRD PARTY CLAIM"), and the indemnified
party intends to seek indemnity hereunder, then the indemnified party will
promptly provide the indemnifying party with prompt written notice of the

                                       19
<PAGE>   25
Third Party Claim, but in any event not later than 30 calendar days after
receipt of such notice of Third Party Claim. The failure by an indemnified party
to notify an indemnifying party of a Third Party Claim will not relieve the
indemnifying party of any indemnification responsibility under this Article
VIII, except to the extent, if any, that such failure prejudices the ability of
the indemnifying party to defend such Third Party Claim.

                  (b) The indemnifying party will have the right to control the
defense, compromise or settlement of the Third Party Claim with its own counsel
(reasonably satisfactory to the indemnified party); provided, however, that the
indemnifying party will not enter into any settlement of any Third Party Claim
which would impose or create any obligation or any financial or other liability
on the part of the indemnified party if such liability or obligation (i)
requires more than the payment of a liquidated sum or (ii) is not covered by the
indemnification provided to the indemnified party hereunder. In its defense,
compromise or settlement of any Third Party Claim, the indemnifying party will
timely provide the indemnified party with such information with respect to such
defense, compromise or settlement as the indemnified party may request. The
indemnified party will be entitled (at the indemnified party's expense) to
participate in the defense by the indemnifying party of any Third Party Claim
with its own counsel.

                  (c) In the event that the indemnifying party does not
undertake the defense, compromise or settlement of a Third Party Claim in
accordance with subsection (b) of this Section 8.4, the indemnified party will
have the right to control the defense or settlement of such Third Party Claim
with counsel of its choosing; provided, however, that the indemnified party will
not settle or compromise any Third Party Claim without the indemnifying party's
prior written consent, unless (i) the terms of such settlement or compromise
release the indemnified party and the indemnifying party from any and all
liability with respect to the Third Party Claim or (ii) the indemnifying party
will not have acknowledged its obligations to indemnify the indemnified party
with respect to such Third Party Claim in accordance with this Article VIII. The
indemnifying party will be entitled (at the indemnifying party's expense) to
participate in the defense of any Third Party Claim with its own counsel.

                  (d) Any indemnifiable claim hereunder that is not a Third
Party Claim will be asserted by the indemnified party by promptly delivering
notice thereof to the indemnifying party.

         8.5. Limitations.

                  8.5.1. Effect of Schedules. Notwithstanding any other
provision of this Agreement, if the Closing occurs, no claim for indemnification
may be asserted under Sections 8.2 or 8.3 with respect to any matter set forth
in the Schedules to this Agreement.

                  8.5.2. Thresholds and Deductibles. Notwithstanding any other
provision of this Agreement or of any applicable Law, no indemnified party will
be entitled to make a claim against an indemnifying party under Section 8.2(b),
on the one hand, or Section 8.3(b), on the other hand, unless and until the
aggregate amount of claims which may be asserted for Liabilities

                                       20
<PAGE>   26
under Section 8.2(b), on the one hand, or Section 8.3(b), on the other hand, as
applicable, exceeds $250,000 and then only to the extent of the excess.

                  8.5.3. Maximum Liability. Notwithstanding any other provision
of this Agreement, (i) the indemnification obligations of Purchaser under
Section 8.2(b) will not exceed $2,000,000, and (ii) the indemnification
obligations of Seller under Section 8.3(b) will not exceed $2,000,000.

                  8.5.4. Exclusive Rights. Except as set forth in Section 6.5,
as between Purchaser and its Affiliates, on the one hand, and Seller and its
Affiliates, on the other hand, the rights and obligations set forth in this
Article VIII will be the exclusive rights and obligations with respect to this
Agreement, the events giving rise to this Agreement and the transactions
contemplated hereby. Without limiting the generality or effect of the foregoing,
as a material inducement to the other parties hereto entering into this
Agreement, each of the parties to this Agreement hereby (a) waives any claim or
cause of action which it otherwise might assert, including without limitation
under common law or federal or state securities, trade regulation or other Laws,
by reason of this Agreement, the events giving rise to this Agreement and the
transactions provided for herein or contemplated hereby, except for claims or
causes of action brought under and subject to the terms and conditions of this
Article VIII and (b) agrees that, regardless of the foregoing provisions, no
party will have any liability in respect of any claim or cause of action that is
or may be brought except in respect of a Liability, and then only to the extent
expressly provided in this Article VIII.

                  8.5.5. Offset. In the event any indemnification obligation
arising under Section 8.3 results in any final, non-appealable Liability of
Seller, Purchaser may, at Seller's option, offset amounts owing by Seller to
Purchaser against amounts owed to Seller by Purchaser under the Notes or any
other obligation.

                  (b) No provision of this Agreement will be interpreted in
